摘  要:
为了确保转鼓试验台系统的精度,需要对其系统进行标定。标定的主要问题是如何对确定量进行测量,并通过何种调节手段,达到显示值与实际值之间的偏差符合精度要求的目的。汽车转鼓试验台转鼓主轴与转鼓电机主轴是重合的,转鼓通过电机主轴将其表面上牵引力传递给电机转子,依靠转子和定子的相互作用,牵引力将被传至与定子固定连接的电机外壳上。因此在电机外壳上安装测力传感器测量电机外壳切线方向上的力实现对转鼓试验台表面牵引力的测量。设计采用双向标定臂可以减小额外扭矩的影响,确保了汽车转鼓试验台表面牵引力的测试精度要求。

摘  要:
The drum test-bed system needs to be calibrated in order to ensure its accuracy,The main problem of calibration is how to measure the determination of quantity so that deviation between the display and actual values can meet the accuracy requirements by some adjustment means,Drum shaft of automobile chassis dynamometer is coincident with the drum motor shaft,the traction of drum surface is transmitted to the motor rotor through the motor shaft,Eventually the traction is transmitted to the motor casing connected with the stator relying on the rotor and stator interaction.Therefore the drum test bench surface traction can be measured from the motor casing tangential force using force sensor mounted on the motor casing.The design adopts bidirectional calibration arm,it can decrease the effect of extra torque to ensure the test precision of automobile chassis dynamometer surface traction
