Characteristics of Ride Comfort and Torsion Elimination of Four-Corner Interconnected Air Suspension System

摘要

摘要: 为提高车辆在不平路面上的行驶平顺性,减小车身所受扭转载荷,提出了一种四角互联空气悬架系统.基于工程热力学和车辆动力学理论,构建了带四角互联空气悬架的整车动力学模型.通过搭建试验台架,验证了所建模型的准确性,并在Matlab/Simulink中进行了仿真分析.研究结果表明:当车辆以20 km/h的速度行驶在对扭路面时,与传统空气悬架相比,四角互联空气悬架可使车身加速度、侧倾角和车轮动载荷分别改善22.5%,24.2%和16.3%, 并消除27.8%的车身扭转载荷,但悬架动行程增大20.6%;连接管路内径在0~10 mm范围增大,互联效果越显著,当车速在10~60 km/h范围时,四角互联空气悬架能有效提升车辆隔振性能,且车速在40 km/h以下消扭效果更加明显.

Abstract: In order to improve the ride comfort and decrease the vehicle body torsion load on uneven roads, a four-corner interconnected air suspension system was proposed. Based on the engineering thermodynamics and the vehicle dynamics theory, a vehicle dynamic model equipped with the four-corner interconnected air suspension was established. Then, the model accuracy was validated by a bench test, and the full vehicle model was simulated under the Matlab/Simulink environment. The results show that when a vehicle equipped with the four interconnected air suspension runs at a low speed on a twisting road, compared to that equipped with the traditional air suspension, the vehicle body acceleration, roll angle and wheel load reduce 22.5%, 24.2% and 16.3%, respectively; the vehicle body torsion load decreases 27.8%; but the suspension dynamic stroke increases 20.6%. Moreover, the interconnection brings about more benefits as the pipe diameter increases from 0 to 10 mm. The four-corner interconnected air suspension can effectively improve the ride comfort when the vehicle speed is in the range of 10-60 km/h, and the torsion elimination characteristics will be more obvious when the speed is less than 40 km/h.
