摘要
从大客车空气悬架平顺性、乘坐舒适性和操纵稳定性的设计角度出发,优化设计空气悬架导向机构参数并与系统特性匹配。在ADAMS虚拟仿真环境下,建立了某型大客车前空气悬架多体动力学模型,通过运动干涉分析和DOE分析,优化匹配悬架参数和系统特性,对比分析优化前后的关键参数。优化结果表明:采用该方法进行悬架的优化设计,优化后转向系统与悬架系统最大干涉量从14.2mm减小至8.0mm,提高了悬架系统的运动特性,并有效降低了系统干涉量。
From the perspective of riding comfort, and handling stability design of bus air suspension, optimal design suspension system parameters and match the suspension characteristic. A multi-body dynamics mode for certain front air suspension bus is established based on ADAS virtual simulation environment, after movement interference and DOE analysis. The research results show that our method applied to suspension optimized design, the maximum interference of optimized steering system and suspen sion system is decreased from 14. 2 mm to 8.0 mm, and it also can promote suspension dynamic characteristics, and reduce the movement interference effectively.
