偏载车辆垂向随机振动分析及二系悬挂参数的优化设计

Vertical random vibration analysis of offset loaded cars and the optimized design of the two-stage spring suspension parameters

本文以22型餐车为例,分析与计算了偏载对车辆垂向随机振动性能的影响,并根据非线性优化设计原理对偏载车辆二系悬挂参数进行了优化设计。

By the example of dining car type 22, the effectsto the vertical random vibration characteristics byoffset loading are analyzed and calculated, and theoptimized design of the two.stage spring suspensionparameters on offset loaded cars is made according tothe non-linear optimized designing principles.
