基于底盘测功机的轮式工程机械底盘动力性能测试

Dynamical property testing on wheel construction machinery chasses using chassis dynamometer

采用工程机械底盘输出功率、底盘传动系统损耗功率为工程机械动力性能的评价指标,通过选用直流电机作为工程机械阻力加载机构,选用合理的滚筒机构以及传感器对工程机械底盘输出功率进行测试.分析发动机的动力传输路线,通过测试数据评判工程机械发动机以及传动系统,对轮式工程机械的底盘维修提供有力的数据支持.

To adopt the chassis output and transmission-system lost powers of construction machinery assessment indicators,the rolling mechanisms and sensors are rationally selected to test the chassis output power by using a DC motor as the resistance loading device.Thereafter,the engine,together with the power transmission route,is analyzed.To assess the engine and transmission system via testing data,this approach provides a data support on chassis maintenance of wheel construction machinery.
