全地域车振动舒适性测试系统开发及应用

Development and Application of Test System for Vibration Comfort of All Terrain Vehicle

为分析评价全地域车(ATV)的振动舒适性,根据标准提出了采用加权加速度均方根值作为ATV振动舒适性客观评价方法,并基于USB2.0开发了可以脱离计算机进行独立采集的便携式数据采集器,并以LabVIEW为平台开发了一套数据处理分析系统,从而构建了ATV振动舒适性测试系统。通过实车振动舒适性道路试验结果表明:系统性能可靠、稳定。

In order to analyze and evaluate the ride comfort of All Terrain Vehicle, an objective evaluation method is developed for ATV vibration comfort by adopting weighted root-mean-square acceleration, along nith a portable USB 2.0-based stand-alone data acquisition device and a LabVIEW-based data processing ＆ analysis system. Combined with them, a vibration testing ＆ analyzing system for ATV is built. The results of road test for vibration comfort on real ATV show that the system is reliable and stable.
