一、前言二、转向器性能试验台的结构特点三、测试系统. 四、测试原理概述试验前应对各传感器进行标定,调整备通道的量程和消除零点飘移,并检查各通道的线性精度。试验时摇臂轴应按《JB2598-81汽车转向器总成台架试验方法》的规定加载。图6给出了该系统的测试原理简图。 1.传动比的测定由于转向轴转角φ和摇臂轴转角β的输出角速度较小(尤其是β),为了提高转换精度,在已选定的光电脉冲发生器的条件下,在传感器与转轴之间分别加入增速环节,测定φ的传感
I. INTRODUCTION 2. STRUCTURE CHARACTERISTICS OF STEERING TEST CABINET 3. TEST SYSTEM 4. Overview of Test Principle Each sensor should be calibrated before the test, adjust the span of backup channel and eliminate zero drift, and check the linear accuracy of each channel. Rocker shaft test should be “JB2598-81 steering gear assembly test method” provisions of loading. Figure 6 shows the system test principle diagram. 1. Determination of transmission ratio As the steering shaft angle φ and rocker shaft rotation angle β output angular velocity is small (especially β), in order to improve the conversion accuracy, in the selected optical pulse generator conditions, the sensor and the shaft Were added to speed up the link between the measured φ sensing
