The document describes the design of a tap-hole drill for Nucor. It discusses various design concepts considered, including different shaft, bearing, motor, and frame designs. It provides key specifications for the drill, including a required torque of 1000 ft-lbs, weight under 4000 pounds, and ability to withstand axial and radial forces of 9000 and 10000 pounds respectively. The final selected design uses a motor/gearbox combination producing 1000 ft-lbs of torque mounted on a steel frame weighing 741 pounds. Finite element analysis confirmed a safety factor of 1.5 under maximum loads.
Radial Fatigue Analysis of An Alloy WheelIJERA Editor
Importance of wheel in the automobile is obvious. The vehicle (car) may be towed without the engine but at the same time even that is also not possible without the wheels, the wheels along the tyre has to carry the vehicle load, provide cushioning effect and cope with the steering control. The main requirements of an automobile wheel are; it must be strong enough to perform the above functions. It should be balanced both statically as well as dynamically. It should be lightest possible so that the unsprung weight is least. The Wheel has to pass three types of tests before going into production, they are Cornering fatigue test, Radial fatigue test and Impact test. In this thesis radial fatigue analysis is done to find the number of cycles at which the wheel is going to fail. The 2D of the wheel was created in MDT, the drafting package and the same was exported to ANSYS, the finite element package using IGES translator where the 3D model of the wheel is created. The wheel is meshed using SOLID 45 element. A load of 2500N was applied on the hub area of the wheel and a pressure of 0.207N/mm2 is applied on the outer surface of the rim. The pitch circle holes are constrained in all degrees of freedom. The analysis is carried under these constraints and the results are taken to carryout for further analysis i.e. fatigue module to find the life of the wheel.

Brief presentation on the manufacture of Aluminium alloy wheels by various methods and the innovations of the present. Made with the help of Siddharth Rawat and Yash Choudhary PS: Download and view in powerpoint for effects.. some text are hidden by pictures.
Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. Ceramic bearings offer many advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, lower friction and more. Ceramic balls are also nonconductive. Ceramic bearings are available in all standard industry configurations such as, angular bearings, thrust bearing, pillow block bearing, needle bearings, and roller bearings.
GEOMETRICAL OPTIMIZATION AND EVALUATION OF ALLOY WHEEL FOUR WHEELERIjripublishers Ijri
Alloy wheels are automobile wheels which are made from an alloy of aluminum or magnesium metals or sometimes a
mixture of both. Alloy wheels differ from normal steel wheels because of their lighter weight, which improves the steering
and the speed of the car. Alloy wheels will reduce the unstrung weight of a vehicle compared to one fitted with standard
steel wheels. The benefit of reduced unstrung weight is more precise steering as well as a nominal reduction in fuel
consumption.
The goal of the project is to suggest optimum geometric shape and material for alloy wheel of a four wheeler.
In the first step previous journals will be studied to understand actual problem, selection of materials, selection of
shape’s and rectification method.
In the next step parametric models will be prepared for further analysis purpose
Evaluation will be done on the model using Ansys work bench for reading results.
The companies of Altra Industrial Motion offer many critical drivetrain products utilized in metal processing applications including heavy duty gear drives, brakes and clutches, geared motors and universal joints

Advanced Design Options for Custom SpringsDesign World
Most engineers are familiar with traditional wire wound (coiled) springs, but in this webinar attendees will learn about a viable alternative known as “machined springs”. Based on the whitepaper “Choosing between Machined and Wire Wound Springs”, the webinar will review differences between these two types of springs along with the advantages of each and application tips. If you work with torsion or compression/extension springs learn why a spring with a Pure Moment and Resolved Moment can significantly improve your products performance. The subject of preventing rotation when a spring compresses or extends will also be covered.
