Simulation of Structural Analysis on Steering Knuckle of the Energy-Efficient Naga Pasa Evo I Weimana Car Using ANSYS Workbench

Abstract

The Steering Knuckle component is the most important part of the vehicle that is connected to the front wheels
with the help of the wheel hub and it is also connected to the steering system and brakes to the chassis. This
study focuses on analyzing the strength of the steering knuckle of the Naga Pasa Evo I Weimana energy-efficient
car in static conditions using 6061 aluminum material. The steering knuckle supports the load of each front
wheel with a maximum weight of 32 kg. Analysis was carried out on the von mises stress value, deformation,
and safety factor. The results showed that the von mises stress on the left steering knuckle was 37.378 MPa and
the right was 34.964 MPa. This indicates that this material has high resistance to stress that occurs because it
is still far from the yield strength limit of 6061 aluminum as its material, which is 259.20 MPa. The total
deformation that occurs on the left steering knuckle is 0.1329 mm and the right is 0.0718 mm, this indicates
that the steering knuckle material experiences elastic deformation which means the material will return to its
original shape when the load is removed. In addition, the safety factor value on the left steering knuckle is
6.9345 and the right is 7.4134. This indicates that the material and design are strong enough and provide great
safety value.
