Design and Analysis of Leveling Shock Absorbers for Vehicle Bodies

A novel leveling shock absorber for vehicle bodies is presented that achieves height adjustment and damping control through purely mechanical design. Traditional magnetorheological dampers and air suspension systems are costly, limiting application in economy vehicles. The proposed shock absorber integrates height adjustment and damping regulation using a height adjustment chamber with one-way valves and pressure relief mechanisms. AMESim simulation models analyzed performance under various road conditions (A-level to D-level roads). Results demonstrate successful vehicle height adjustment (−2 mm to +4 mm) and adaptive damping characteristics. The system provides higher comfort on bumpy roads and improved stability on smooth roads compared to conventional dampers. Dynamic response analysis confirms consistent adjustment times, validating the shock absorber’s effectiveness in enhancing vehicle stability and control accuracy at reduced cost.
