•
an important role during design stages. The paper focused on stress analysis of the chassis using finite element package ANSYS. The current work contains the load cases & boundary conditions for the stress analysis, deformation analysis of chassis.
• •
Key Words: stress analysis, deformation analysis of chassis,chasis design.
STEERING •
Introduction-Chassis is a French term and was at first
used to denote the frame components or Basic Structure of the vehicle. It’s the rear bone of the vehicle. A vehicle without body is termed Chassis. The elements of the vehicle like powerhouse, gear, Axles, Wheels and Tyres, Suspension, dominant Systems like Braking, Steering etc., and conjointly electrical system components mounted on the Supra Chassis frame. It combines all the elements together with the body. Therefore it's conjointly known as Carrying Unit.

Cockpit Opening &Cockpit Internal Cross Section must be as per the template Any portion of frame which might be in contact with driver helmet must be padded. . Firewall &Floor Close-out must be of suitable material as per the rules. Restraints, its attachments and mounting must be strong enough to withstand a force of 890N. The suspension system with shock absorbers must have minimum travel of 2 inches. The smaller track of the vehicle must be no less than 75% of the larger track. The wheels of the car must be 8.0 inches or more in diameter. The car must have a wheelbase of at least 1525 mm (60 inches).

Limitation of Engine displacement is set to below 610cc. The throttle must be actuated mechanically, i.e. via a cable or a rod system. Intake System Restrictor of 20mm must be used. The maximum permitted sound level from the vehicle is 110 dBA.
Table -1:
SUSPENSION & WHEELS •
Allowable free play for the steering system is limited to 7 degree measured at steering wheel. The steering wheel must be mechanically connected to the wheels.
ENGINE
CHASSIS •
Brake pedal must be designed to withstand a force of 2000N. The braking system must act on all four wheels and be operated by a single control. The vehicle must be equipped with two (2) master switches which form part of the shutdown system.
