【Abstract】 Based on the principle of mehanics, the paper has given the theoretical analyses on the sensable problem of the piezo-electric dynamometer crosstalk, and deduced the formulas of crosstalk εxz and εyz. Experiment results indicate that the conclusions are correct, and the calculated values are relatively conformable with the experimental values. This study will provide the theoretical foundation for the structure improvement of the piezo-electric quartz force sensor and the optimization design of the dynamometer更多还原
