摘　　要：在单滚筒底盘测功机中,测力系统以测力传感器为核心,安装在电力测功机的外壳上,再配合力臂、底座、处理器等构成整个系统。文章提出来底盘测功机在测试过程中对测力系统进行校准的必要性,在此基础上,对测力系统的零点、满量程进行了标定,并设计双向标定臂对测力传感器的线性度、重复性进行了检定,试验结果显示,论文所采用的测功机测力系统最大偏差为8N,具有良好的线性相关性与重复性,可以满足测试要求,且此方法具有简单、准确、快捷的优点。In the single cylinder chassis dynamometer,The force sensor is the core of the force sensor,It is installed on the pow er dynamometer housing,coupled w ith the structure of the w hole system,the base,arm processor. In this paper,the necessity of the calibration of the dynamometer in the course of the test is carried out. Based on this,the zero point and the full scale of the measuring system are calibrated,and the linearity and repeatability of the bidirectional calibration arm are designed. The experimental results show that the measured dynamometer test system the maximum deviation 8N,w ith good linear correlation and repeatability,can meet the test requirements,and this method has the advantages of simple,accurate and fast.
