Abstract

In the automotive industry, lightweight design has become a key strategy for reducing environmental pollution and improving energy efficiency. As a core component of the suspension system, the lightweight design of steering knuckles significantly impacts the overall vehicle performance. To ensure stable operation and good dynamic performance under various working conditions while reducing mass, this study uses ANSYS software to perform topological optimization on the steering knuckle structure with the comprehensive goal of improving static stiffness and the first-order modal frequency. Through optimization, the mass of the steering knuckle has been effectively reduced to 1.075 kg, and the first-order natural frequency has been increased to 551 Hz, demonstrating excellent dynamic characteristics and significantly enhancing the overall performance level of the steering knuckle.
