一、概述关于汽车动态前轮前束试验台的校准方法,目前尚无国家检定规程或校准规范可依据,针对实际校准工作的需要,本文介绍了一种汽车动态前轮前束试验台的校准方法,并对校准结果进行了不确定度分析。车轮的旋转平面相对汽车纵向轴线的内夹角称为单轮前束角,车轮前缘向内为正,向外为负。汽车动态前轮前束试验台的基本原理是左右两组滚筒由电动机驱动以20km/h左右的速度旋转带动汽车前轮旋转,滚筒组安装在可以转动的浮动盘上。由于前束的 First, an overview on the car front beam front beam test bench calibration method, there is no national verification procedures or calibration specifications can be based on the need for actual calibration work, this article describes a dynamic front wheel beam test bench calibration Method, and the uncertainty of the calibration results were analyzed. The inner angle of the rotation plane of the wheel relative to the longitudinal axis of the vehicle is referred to as a single toe angle, the leading edge of the wheel is positive inward and negative outward. The dynamic principle of the front wheel toe test bed is that left and right two groups of rollers are rotated by a motor driven at a speed of about 20 km / h to drive the front wheel of a car to rotate, and the roller group is mounted on a rotatable floating plate. Because of the toe
