Abstract

Steering knuckle is one of the indispensable parts of the vehicle, which is amalgamated with directing, suspension, wheel hub and brake to the body of the vehicle. It undergoes varying loads subjected to different road conditions without affecting the vehicle steering performance and other desired vehicle characteristics. The heaviness of the vehicle is continuing expanding because of extra deluxe and security highlight. The expanding weight of the vehicle influences the fuel effectiveness and general execution of the vehicle. Controlling knuckle is one of the discriminating parts of the vehicle.

In the present work steering knuckle was designed and developed by using 3D modelling software and its results were validated with the previous researchers work as well as failure analysis. The aim of the work was to optimise the size and weight of the steering knuckle without compromising its strength, frequency and stiffness. The shape improvement of the knuckle and topology optimization is done using SOLIDWORKS version 17.0 and analysis is carried out in ANSYS 16.0. The wheel assembly is attached to the spindle of the knuckle where the wheel rotates while knuckle is in stable plane of motion.

The Result of this paper gives a piece of brief information about what is the difference in the initial cad model and the final cad model based on the boundary condition and analytical result obtain from the ANSYS software. it can be concluded that parameter which is effective for the design and fabrication such as total deformation, equivalent stress and weight of component changes from 0.35mm, 90.15Mpa, 1.52kg to 0.273mm, 92.82Mpa, 0.734kg respectively..
