摘要
针对高速客车轻量化设计引起的车体结构动态特性下降的问题 ,探讨了改善车体动态特性、提高一阶垂向弯曲振动频率的几种可行途径 ,介绍了国际上近几年提出的采用形状记忆合金和高阻尼合金改善结构动态特性的新方法。
In order to solve the problem of dynamic behavior deterioration caused by lightening design of high speed railway passenger cars, several feasible methods for improving the dynamic behavior and increasing the first order vertical bending frequency of car-body are discussed in this paper. Two new ways put forward in recent years internationally to improve the dynamic features, the shape memory alloy and high damping alloy, are described.
