| 摘 要： | 传感器的静态耦合是制约多维车轮力传感器（WFT）测量精度的一个主要因素，WFT的耦合主要为线性耦合。针对标定WFT时不能施加单维力的情况，用迭代法实现了线性解耦。时WFT的耦合率矩阵进行了计算，并进行了耦合分析。对汽车道路试验数据进行了解耦，并与不解耦的结果进行了对比。结果表明：经线性解耦后，WFT的耦合误差基本被消除，测量精度得到了提高。

| Abstract: | The static couple of multi-dimension wheel force transducer(WFT) is one major factor of limiting its measuring precision,and the couple of WFT is mainly linearity.Since single dimension force cannot be put on WFT when it is calibrated,iterative method is used for linearity uncouple.Cross-coupling matrix of WFT was computed, and characteristics of crosstalk was analyzed.Data in motor vehicle road test are uncoupled,and the result was compared with the result of coupled.The results suggest that crosstalk error is almost eliminated and the measuring precision is improved with linearity uncoupling. |
