30kN.m工程机械车辆刹车制动压力扭矩试验机
Construction Machinery Vehicles Brake Moment Tester
功能参数：
→30kN.m工程机械车辆刹车制动压力扭矩试验机，评估测试制动器连续运转时，制动气压力变化对制动力矩的影响。制动力矩变化对制动气压力的影响。温度变化对制动器性能的影响。
→去除制动器衬片衬块和制动鼓盘摩擦表面的油脂、涂料等异物，将制动器样品按实车状态安装到HRJ疲劳试验机上，按连接螺栓螺母规定拧紧力矩紧固。进行制动器磨合试验和制动器疲劳强度试验。检查鼓式制动器支承部位销孔变形，制动蹄铁变形及破损，摩擦衬片的移位，制动底板的变形，安装部位变形及松动。检查盘式制动器制动衬块插入部位变形，制动钳的变形，制动衬块变形及破损，安装部位变形及松动。
→汽车制动器疲劳性能试验温度测量装置，测量记录制动器温度，制动衬片块温度测量，制动鼓盘停止转动后15s内温度变化测量。制动液温度变化测量，制动试验动作解除后间隔1min制动液温度变化测量。
→20bar/s气压控制，制动鼓减速度制动力矩3.5m/s2或5.9m/s2，制动周期5s±0.5s，制动时间少于1.5s，制动鼓盘转角大于15°，制动次数5000次/50000次。载波频率信号调理。
→绘制制动鼓盘转角-时间曲线，制动力矩-时间曲线，制动鼓盘前进方向转动时间曲线，制动鼓盘返回时间曲线，制动时间曲线，制动力矩稳定时间曲线，制动鼓盘空转时间曲线，制动器温度控制曲线。
