Abstract: Magnetorheoloical damping technology, as an advanced semi-active control technology for automotive suspensions, has received widespread attention over the past few decades. This study aims to explore the application of magnetorheological damping technology in automobile suspension systems to enhance vehicle stability and comfort during driving. By analyzing the working principle of magnetorheological fluid and its rapid response capability under magnetic fields, an automotive shock absorber based on magnetorheological damping technology is designed. Laboratory tests are conducted according to automotive shock absorber performance testing standards, along with subjective evaluations of automobile handling and stability performance. The results indicate that the magnetorheological damper can effectively and rapidly adjust the damping force, adapting in realtime to road conditions, significantly reducing vehicle body vibrations, and improving driving comfort, showcasing a clear performance advantage over traditional shock absorbers. This study validates the effectiveness of magnetorheological damping technology in enhancing automobile performance, providing theoretical support for further product development and bulk automotive applications.
