一前言底盘转鼓试验台是在室内进行汽车行驶性能试验的设备。它以转鼓代替无限平坦的道路,使汽车的驱动轮在转鼓上运转,从而进行汽车行驶性能试验。试验时,给鼓轴以汽车在实际道路上行驶时所受的相同负荷(行驶阻力),并在尽量接近实际行驶状态下,作各种测量(图1)。 A preface Chassis drum test bench is a vehicle for performance testing indoors equipment. It is the drum instead of infinite flat road, the car’s driving wheel on the drum to run, so as to conduct the car driving test. During the test, the drum shaft is subjected to the same load (running resistance) as the car is traveling on the actual road and various measurements are made as close to the actual driving conditions as possible (Figure 1).
