30kN.m工程機械車輛刹車制動壓力扭矩試驗機
Construction Machinery Vehicles Brake Moment Tester
功能參數：
→30kN.m工程機械車輛刹車制動壓力扭矩試驗機，評估測試制動器連續運轉時，制動氣壓力變化對制動力矩的影響。制動力矩變化對制動氣壓力的影響。溫度變化對制動器性能的影響。
→去除制動器襯片襯塊和制動鼓盤摩擦表面的油脂、塗料等異物，將制動器樣品按實車狀態安裝到HRJ疲勞試驗機上，按連接螺栓螺母規定擰緊力矩緊固。進行制動器磨合試驗和制動器疲勞強度試驗。檢查鼓式制動器支承部位銷孔變形，制動蹄鐵變形及破損，摩擦襯片的移位，制動底板的變形，安裝部位變形及松動。檢查盤式制動器制動襯塊插入部位變形，制動鉗的變形，制動襯塊變形及破損，安裝部位變形及松動。
→汽車制動器疲勞性能試驗溫度測量裝置，測量記錄制動器溫度，制動襯片塊溫度測量，制動鼓盤停止轉動後15s內溫度變化測量。制動液溫度變化測量，制動試驗動作解除後間隔1min制動液溫度變化測量。
→20bar/s氣壓控制，制動鼓減速度制動力矩3.5m/s2或5.9m/s2，制動周期5s±0.5s，制動時間少于1.5s，制動鼓盤轉角大于15°，制動次數5000次/50000次。載波頻率信號調理。
→繪制制動鼓盤轉角-時間曲線，制動力矩-時間曲線，制動鼓盤前進方向轉動時間曲線，制動鼓盤返回時間曲線，制動時間曲線，制動力矩穩定時間曲線，制動鼓盤空轉時間曲線，制動器溫度控制曲線。
