摘　　要：根据"力偶矩在平面内移动,其值不变"原理研制出新型压电式四向无定心钻削测力仪。轴向力和切向力分别采用两片X0°和Y0°晶片对装;扭矩采用4对Y0°晶片均布在同一分布圆上,各晶片电荷灵敏度方向与分布圆相切,即可实现无定心扭矩测量。标定结果表明,该测力仪轴向力、径向力和扭矩的线性度和重复性均小于1%,横向干扰小于5%,完全达到了石英力传感器的使用要求。Based on ＂the couple can arbitrarily move in the application plane, its value remains unchanged＂, a new type of four component no-centering drilling dynamometer is designed. The thrust measuring cell is made of two X0°-Cut quartz discs, and the radial force measuring cell consists of two Y0°-Cut quartz discs. Four pairs of Y0°-Cut quartz discs, whose maximum sensitivity directions are tangent to the distribution circle, constitute the no-centering torque measuring cell. The static calibration results show that both the linearity and repeatability of the thrust, radial force and toque are less than 1%, and the cross talks are also less than 5 %, which have full reached the application requirements of piezoelectric quartz sensor.
