Furthermore, the simulation parameters on the dynamic performance of curve negotiation in theoretical geometric state and track random irregularity state are compared and evaluated by using the ride quality index. 对比轨道理论几何形位状态和轨道随机不平顺状态下曲线通过动态性能仿真值,并用乘坐舒适性指标进行了评价。
In order to improve the efficiency of sensitivity analysis, a four-factor and four-level orthogonal experiment table is designed to construct the polynomial response surface model between the ride quality Sperling index and suspension parameters. 为提高灵敏度分析效率,设计了4因素4水平正交试验表,构建了垂向平稳性Sperling指标与悬挂参数之间的多项式响应面模型,求得了灵敏度,并对所求灵敏度的精度进行了分析。
