  • We didn't rely on the references or online essays. However we used our experience in the workshop that helped us to create this system. However I advise you to check the German system. Chinese is not bad. Japanese system is about a building that has a lot of parkings insdie and it's very big project. We built 4 projects and all failed. What you see now is the last one and it success.

  • 5. Mechanical Double Parking System 20122 Abstract Due to the increase in the number of vehicles on the road, traffic problems are boundto exist. This is due to the fact that the current transportation infrastructure and car park facilitydeveloped are unable to cope with the influx of vehicles on the road. To alleviate theaforementioned problems, the smart card parking system has been developed. With theimplementation of the parking system, patrons can easily locate and secure a vacant parkingspace at any car park deemed convenient to them. Here in UAE and especially inside Abudhaicity a significant growth in many life sector lead highly expansion in population as a result ofthat, a raped increase in cars number that used. The thought of alternative method for car parkingis caused by that exciting parking area provided is not enough to handle that growth in carsnumber.3 Introduction The number of cars on roads is increasing continuously and rapidly from the recent years;unfortunately most parking spaces did not increase as the cars did ending up with endlessparking problems. As mechanical engineering students, we hope that our contribution findsacceptance in solving this problem that is really complicated in our country. Automated Car Parking is a method of automatically parking and retrieving cars thattypically use a system of pallets and lifts. The intention is to compact more cars in the samespace, reduce the space needed to park the same number of cars. Automated car parks can besituated above or below ground or a combination of both. As the system removes the need for driveways and ramps, the floor area and the volumeof the parking station itself can be more efficiently used .Automated parking systems can bedesigned to fit above or below ground, allowing for flexible usage of land space; this means the 5footprint can be reduced to one-third of the land required by conventional car parking solutions.Cost effective on a number of fronts, Automated parking systems are about making the best useof available space above and below ground. With less environment impact and time impact, MECH N450 Dr. Yw Chan | HCT, Abu Dhabi
  • 6. Mechanical Double Parking System 2012reduced opportunities for theft and vandalism and real cost benefits, automatic parking is thenew watchword in urban planning .There is an overwhelming need for these systems because ofincreasing traffic. These systems can be integrated with in consumer based electronic devices.The individual components are installed inside this structure for its operation. In our project, we have given a finished project design about double parking system. Wehave been asked to build this project. We don’t really know whether the project will success ornot. We have tried to build it but it wasn’t work because the platform wasn’t straight what itmoves. In this case, we have designed new double parking system that has better mechanicalmovement and more safety. It also ensures smooth movement and straight platform movement.With this system, we are sure that it will increase the capacity of parking areas inside Abu Dhabi.4 Project management design4.1 Business Model Abu Dhabi has idea to increase the parking areas by making a building that has onlyparking for cars. This is good idea. However, the costs of making building are very expensive. Itneed a lot of time to return the budget. The ministry of transportation has significant interest onsolutions to the car parking problems. They will study the project after it finish and will decidewhether it is acceptable and useful in Abu Dhabi.4.2 Operation Model The double parking system is only useful in open areas. That’s because on building, it willtake more height which takes more space so it’s not very useful. The double parking system willnot be operated by the drivers. Therefore, there will be trained parking service supervisor tooperate and park the cars to ensure more safety because we can’t rely on customers. 6 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi

Mechanical Double Parking System 20124.10 Priority Matrix Time Performance Cost Constrain Enhance Accept Table 1, priority of matrix4.11 Summary One of the courses requires us to build a mechanical parking system. The number of the carsis increasing in Abu Dhabi and this will make the roads busy and not so many parking areas areavailable. As mechanical engineering students, we are seeking to solve this kind of problem inour country. The main objective of this project is to redesign and build a mechanical parkingsystem to get rid of the problem in Abu Dhabi. The idea is about having a system that lift a carabove another car. It’s like two cars above each other. As you can see from (table 1), we willanalysis from project management prospect. 9 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi
  • 10. Mechanical Double Parking System 20124.12 Time-constrain As this project is one of my courses requirements, we as a group must finish it on week 15,otherwise we can’t success this course and we can’t graduate. We even only have two hoursweekly just to build the project. Two hours are not enough to build a serious project. Therefore,we decided to work in our free time. The project is not real big project, it’s only prototype.However, it needs a lot of work such as welding which will take long time.4.13 Scope-enhance As I said above, we will redesign the project. Our teacher gave us a completed mechanicalparking system design that has been made 3 years ago by HCT students and he told us to buildit. However, not any documents design can be built. We are not sure that this design will work.We can only be sure when we build it and check whether it works or not. We have decided tobuild a toy-type, even smaller than prototype just to check the performance. It appeared thatthis project should have a lot of editing and it should be enhanced and redesigned. The givendesign wasn’t successful so we redesigned completely.4.14 Cost-accept The frame of the project is consisting of normal materials and it doesn’t have a lot of pieces.The only parts that will costs are the motors that will lift the car to up and move the car downto the ground. Beside, most the materials we need are in the mechanical workshop in highercollege of technology as well as the final project will be small as a prototype not the actual one.In short, the project itself will not cost a lot of money so it doesn’t need strong budget. 10Therefore, we accept any amount of money.

Therefore, we moved to another design and modified it in betterway. After that, we found that the movement is smooth and the platform was leveled.Expected effects after that change:1. Increase the working times hours because we need to start again new design.2. Buy new material for the new design.3. Draw new AutoCad design for the new idea.4.

So we the FEA (finite elementanalysis) are introduced. The finite element method is a good choice for solving partialdifferential equations over complicated domains (like cars and oil pipelines), when the domainchanges (as during a solid state reaction with a moving boundary), when the desired precisionvaries over the entire domain, or when the solution lacks smoothness.ANSYS is used because it offers a comprehensive range of engineering simulation solution setsproviding access to virtually any field of engineering simulation that a design process requires,and by this it will assess the design from a set of calculations regarding the movement, andmaterials. 57 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi

Mechanical Double Parking System 2012The following diagram will show the type of material used in the frame and some specificationsthat were proven to be helpful.1018 Mild SteelAlloy 1018 is the most commonly available of the cold-rolled steels. It is generally available inround rod, square bar, and rectangle bar. It has a good combination of all of the typical traits ofsteel - strength, some ductility, and comparative ease of machining. Chemically, it is very similarto A36 Hot Rolled steel, but the cold rolling process creates a better surface finish and betterproperties.Our conditions are to have a safety factor of 3 and a high tensile strength of 440 MPA, so theplatform will carry three times the weight of the car.10 Frame selection and sizingWe selected mild steel for our frame because it is has a low price while can be used in many 58applications. This kind of steel contains 0.18%, therefore it’s neither brittle nor ductile. It ischeap and malleable. The surface hardness can be increased by carburizing(is a heat treatment MECH N450 Dr. Yw Chan | HCT, Abu Dhabi

Rubber standsFigure 13, rubber stands prospect The diameter for the circular rubber base or stand is d= 8cm and the thickness is 1cm. this product is easy to find if ordered from small shops that manufacture rubber. 11.2 Cable and pulley sizing Our winch system is using a polyethylene fishing line as connecting rope for the weight lift up during ascending and descending process. This cable is passing through many pulleys in which the main purpose of them is to change and re dispute the force direction and also guiding the cable that is connecting the winch drum and upper platform. 60 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi

It sticks stiffly outfrom the main line and holds the hook in the correct position. With such a high breaking strain(180 kg at just 1.60 mm diameter), even a Halibut of 150 kg would not be a problem. HarunaSeamaster Hard Leader is even successfully used in professional fishing and valued for itstransparency. 62 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi
  • 63. Mechanical Double Parking System 201211.3 Stretch or Elasticity Most braided lines have very low stretch of between 1% and 8% allowing unique anddirect control and contact to your bait. Just for predator fishing with modern methods, such asdrop shot fishing, a well braided line is without doubt the best line to use. An important issue toconsider however that is a low-stretch-line means a much higher load on the unit, because eachstrike goes directly through the rod and reel. It means that with braided lines it is particularlyimportant to correctly set the reel brake. Our tip: Because of its low stretch, a braided fishing lineis not always the appropriate choice for every angling method. Every ordinary fishing reel nowhas a spare spool, so we recommend filling one spool with a braid and the other one with amonofilament, so that you are perfectly prepared for every situation.Attributes:• Ideal also for professional sea fishing Diameter Ø mm 0.60 0.75 0.90 1.05 1.20 1.45 1.6 Kg 30 42 60 80 100 150 180 63 MECH N450 Dr. Yw Chan | HCT, Abu Dhabi Figure 15, side view of the project
  • 64. Mechanical Double Parking System 2012 As you can see from (figure 15), that shows the mechanical movement of the Aluminumplatform. Platform is placed and fit on the frame with bases that makes space between theplatform and the frame. The platform is attached with two arms of steel. The red arm which isfront from car prospect, is cut from the middle as a semi circle that is used to house the pulley.The rear yellow arm is another is also attached for more operation control. The length of botharms and the place of the holding determine safe operation that makes the platform movesmoothly and goes down without touching the frame or the below car. Under the platform, thereis piece of steel that is attached to both yellow arms which hole and platform and make it morestabilized. On the front side of the project, There are 2 pulleys that is attached with a DC motor.What drive the pulley is the cable that is attached from pulley to both rear and front arms passingthe tensioner. The purpose of the tensioner is to not make the cable loose which provide safemovement. After the tensioner, the cables goes all the way to the small pulley on the back of theframe that is help to pull the platform and move it. Under the platform, spring limiter is attachedto provide the possible needed spring movement. To complete the movement of pushing andpulling the platform with safe operation, there is also another small pulleys on front side of the 64frame that you can see it in ( figure 15) on the highest part of the frame.
