Abstract: This paper introduces the four-channel road simulation test and its assessment strength of main vehicle systems. The correlation between bench test and road test is compared and analysed by collecting the acceleration, strain and force of various parts. It helps to effectively identify the problems in the test process, while is true or false. And it provides reliable test data for design.

Key words: Four-channel; Road simulation test; Correlation analysis

摘要： 文章介绍了四立柱道路模拟试验及其对车辆各主要系统的考核强度。通过采集各零部 件的加速度、应变或受力，对比分析台架试验与道路试验的关联性，有效辨识试验过程中出 现的“真”“假”结构性问题，为设计研发提供可靠的试验数据。
