摘要
通过理论分析,导出了前后轮距不同以及后轮双胎时路面对四轮车辆的输入谱矩阵。与试验数据对比证明,本文提出的模型更为符合实际情况,而且具有很大的通用性,因此可为汽车随机振动及平顺性的的理论分析和试验工作提供了较为合理的谱矩阵数学模型。
Through theory analyses, this paper presents a road input spectra array to four-wheel vehicle which may have different wheel base or may have double tyres at rear wheel. Comparing theoretic results with test data,the spectra array presented in the paper agrees much better with real case, and it's suited for different type of four-wheel vehicle. Therefore, it can be used as the road input spectra array to four-wheel vehicle in the random vibration analysis or ride comfort analysis of the vehicle.
