摘要

目的解决车辆多轴轴耦合台架试验耗时长、花费大以及振动环境模拟精度低等问题。方法将雨流投影方法运用到多维载荷加速处理中,利用传统雨流滤波法和多轴雨流投影滤波方法分别对特种车辆部件实际所受的多轴载荷进行加速处理,对加速后的多维载荷信号开展基于时域波形再现的振动环境模拟,以更有效地利用轮式车多轴轴耦合试验台开展加速疲劳试验。结果对比加速前后的多维载荷信号,在时域、频域、损伤域基本一致的前提下,多维载荷信号时间压缩了50%,多轴振动环境的模拟精度大于80%。结论采用该方法开展车轮加速疲劳试验,能够精确再现被试件的实际振动环境。通过实际试验验证,可以很好地再现故障出现的时间和形式,与实际野外路试结果十分吻合。

Abstract

The work aims to solve the problems of long time, high cost, and simulation accuracy of vibration environment in multi-axle coupling bench test of vehicles. The RP method was applied to the multi-dimensional load signals acceleration processing. The rain-flow filter method and the RP filter method were used to accelerate the multi-dimensional load signals applied to special vehicles and then the vibration environment simulation test was carried out for the accelerated multi-dimensional load signals based on the time wave reconstruction theory, so as to carry out accelerated fatigue test more effectively by the multi-axle coupling test bench of wheeled vehicles. Compared with the original multi-dimensional load signals, under the same time domain, frequency, and damage domain, the signals filtered by RP filter were compressed by 50% and the simulation accuracy of vibration environment in multi-axle coupling test was greater than 80%. The wheel acceleration fatigue test is carried out by the proposed, which can accurately reproduce the vibration environment. The time and forms of failure can be reproduced effectively through the verification by test, which are consistent with the vehicle field test results.
