The suspension System of an automobile is one which separates the wheel/axle assembly from the body. The primary function of the suspension system is to isolate the vehicle structure from shocks & vibration due to irregularities of the road surface.
Chassis is the main support structure of the vehicle which is also known as ‘Carrying Unit’. It bears all the stresses on the vehicle in both static and dynamic conditions.”
This is Mechanical project report on Fabrication of an Active Air Suspension System. Air ride suspension
carries the load on each axle with a pressurized air bag just as a high pressure balloon. This system provides
the smoothest and most shock free ride of any of the known vehicle suspension system. An air suspension
includes a multiple air spring assemblies that each includes a piston airbag and a primary airbag mounted over
the piston airbag. The main and piston air bags each have a variable volume that is controlled independently
of the other for active suspension control.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Difference Between Air Suspension System And Rigid
Suspension System
Advantages & Disadvantage & Application
3. Air Suspension System
Air springs are used in air
suspension systems. The
installation and configuration of air
suspension systems varies for
different makes and models but the
underlying principle remains the
same. The metal spring (coil or
leaf) is removed and an airbag also
referred to as an air spring, is
inserted to fit in the place of the
factory spring. When air pressure is
supplied to the airbag, the
suspension can be adjusted either
up or down (lifted or lowered).
4. Air Spring
Air spring is nothing but flexible bellows, usually made from
textile-reinforced rubber, containing compressed air which is used
to carry the load on vehicles. The air pressure inflates the bellows
and raises the chassis from the axle. Air springs have elasticity or
“springiness” when it is compressed. It is used on many heavy-
duty trucks, trailers, and buses on the road today.
Types Of Air Spring
● the double-convoluted,
● the tapered-sleeve,
● the rolling-sleeve.
5. The double-convoluted design looks like small tyres
kept one over the other. These type of air springs
generally has more load capacity, a shorter stroke,
and a more progressive spring rate which is best
suited for use on most front suspensions where the
spring sits considerably inboard of the suspension’s
load point. This has the effect of multiplying load
capacity requirements while dividing travel
requirements
Tapered- and rolling-sleeve air springs are smaller in
diameter with a longer stroke and a more linear spring
rate. They are best suited for most rear-end applications
because there has more travel requirements and fewer
load-capacity requirements
6. Types of air suspension
1. Bellow type air suspension
2. Piston type air suspension
3. Elongated bellows air suspension
1.Bellow type air suspension
This type of spring consists of rubber
bellows. The bellows are made into
circular sections having two
convolutions for proper functioning as
shown in picture. So, a bellow type
air suspension replaces the coil spring
7. Piston type air suspension
This spring has a metal-air
container in the form of an
inverted drum. The drum is
connected to the frame. A sliding
piston is connected to the lower
wishbone. A flexible diaphragm
provides a seal. The diaphragm
is tightly connected at its outer
circumference to the lip of the
drum and at the center to the
piston as shown in picture
8. Elongated bellows air spring
When this system of suspension
is employed to the rear axle of
the vehicle, then elongated
bellows are used. These bellows
are of approximately rectangular
in shape but they are with semi-
circular ends having generally
two convolutions. These elbows
are arranged between the rear
axle and the frame of the
vehicle. To resist the torques and
thrusts, the radius rods are used
at the rear axle.
10. Components Of Air Suspension System
1. Air filter
2. Air Accumulator
3. Relief valve
4. Air spring
5. Lift control valve
6. Return valve
7. Supply line
Construction of Air Suspension :
The layout of an air suspension system has been shown in Fig. The four air springs, which
may be either the bellows-type or the piston type, are mounted on the same position where
generally the coil springs are mounted. It also consists of an air compressor, air
accumulator, relief valve, lift control valve, leveling valve, and pipeline.
11. Working of Air Suspension
An air compressor takes the atmospheric air through
a filter and compresses it to a pressure of about 240
MPa, at which pressure the air in the accumulator
tank is maintained, which is also provided with a
safety relief valve. This high-pressure air goes
through the lift control valve and the leveling valves,
to the air springs. Each air spring is filled with
compressed air which supports the weight of the
vehicle. The air gets further compressed and absorbs
the shock when the wheel encounters a bump on the
road.

13. Difference Between Air Suspension System And Rigid Suspension System
Air Suspension System Rigid Suspension System
1. In this system air springs or air bellows are used 1. In this system leaf spring or
coil spring or both are used.
2. In air suspension system wheel deflection is
controlled by automatic control devices.
2 In this system there is no
automatic control device.
3. Increased riding comfort and decreased noise
level.
3 Riding comfort is less as
compared to the air suspension
system.
4. The springing rate varies much less between the
laden and unladen conditions, as compared with
that of conventional springs.
4. The springing rate is more as
compared to the air suspension
system.
14. Air Suspension System Rigid Suspension System
5. Stiffness of the system increases with an
increase in deflection.
5. Stiffness of the system decreases with an
increase in deflection.
6. Application: Volvo bus, Luxury cars 6. Application: Heavy and medium-duty vehicles,
passenger cars, etc.
7. Reduced fatigue to the driver and passenger. 7. More fatigue to the driver and passenger as
compared to the air suspension system.
8. It consists of Compressor, reservoir, leveling
valve, air springs or air bellows, etc.
8. It consists of leaf spring, coil spring, shock
absorber, shackle joint, bracket, etc.
15. Advantages of air suspension
1) A variable space for wheel deflection is put to optimum
use by virtue of the automatic control devices
2) Because the vehicle altitude is also constant, changes in
headlamp alignment due to varying loads are avoided.
3) The spring rate varies much less between the laden and
unladen conditions, as compared with that of conventional
steel spring. It reduces the dynamic loading.
4) The improved standard of ride comfort and noise
reduction attend with air springs reduces both driver and
passenger fatigue
16. Disadvantages of Air Suspension System
● Higher initial cost
● Occupies more space.
● The maintenance cost is more.
● Due to lack of friction damping is necessary due to road
shocks.
Application of Air suspension System
The air suspension system is used in Modern Buses, Volvo, passenger
cars, and trucks for comfort ride.
