基于虚拟仪器的车辆平顺性舒适度指示器仿真研究

Research for Simulation of the Riding Comfort Indicator of Vehicle Based on Virtual Instrument

介绍了车辆振动舒适度的评价方法及虚拟仪器技术。基于虚拟仪器,将车辆座椅处的振动加速度均方根值与人对车辆振动舒适性的主观感觉相结合,以汽车综合平顺性指标———车辆平顺性舒适度CV为参数,对车辆振动舒适度进行了计算及指示器的界面仿真,对解决汽车振动舒适性难以评价及比较的问题进行了有益的尝试。

The methods of evaluating comfortable degree of vibration of vehicle and virtual instrument are introduced. Based on virtual instrument, associating the root-mean-square-value with people＇s feeling for the vibration of vehicle, taking the riding comfort of vehicle, Cv, as parameter, this paper computes the comfortable degree of vibration and simulates the interface of indicator.
