Abstract

The force offered by the driver of an automotive in navigating the vehicle along the road is transmitted through the steering wheel through the steering system up to the front wheels. Manual or hydraulic mode is utilized to turn the wheels. This dissertation work aims to focus on the ‘universal joint’ also called the ‘yoke’ .The component have two halves that pair to effect a flexible axial joint while accommodating misalignment. Forces are transmitted through the ‘spider’ or the ‘web’ within the two halves. This work attempts to evaluate the strength of the joint to avoid failure. Besides, the scope for mass reduction in realizing a lighter component shall also be investigated using the methodology for ‘Topology Optimization’ while engaging `Altair Hyperworks - OptiStruct’ in dealing with problem. Mathematical treatment is offered to understand the extent of forces to be borne by the joint during its operation. A tentative target of about 2% mass reduction is set while pursuing this work. The result determined by the computational methodology shall be validated through physical experimentation.The force offered by the driver of an automotive in navigating the vehicle along the road is transmitted through the steering wheel through the steering system up to the front wheels.
