摘要
为获得准确的整车簧载质量与非簧载质量,利用汽车簧载部件与非簧载部件的相对运动特性,以不同车身姿态的整车重心高度作为基准,推导计算非簧载质量所需参数,并基于实车重心高度测量结果及其他参数计算相应的非簧载质量,最后通过实车拆解称重获得实际非簧载质量。试验结果表明:非簧载质量计算结果与实测结果接近,证明了该方法的可行性。
To obtain the vehicle’s sprung mass and unsprung mass accurately,this research used the characteristics of the relative positions of the sprung mass and unsprung mass,with the height of the vehicle’s center of gravity with different body attitude as the reference,to derive the parameters required to calculate the unsprung mass,then calculate the corresponding unsprung mass based on the measured vehicle gravity center height and other parameters.Finally,the unsprung mass was weighed by disassembling a real vehicle.Test results show that the results of calculated unsprung mass are close to those of measured results,which proves that the research approach is feasible.
