摘要: 本实验验证了一种集成于工装夹持器中的石英谐振式力学传感芯片的应用。该夹持器设计了应力集中凹槽以安装芯片，通过计频器读取芯片的频率信号，并将其与油压装置施加的力进行对比标定，得到整体线性度98.7%、重复性95.2%、迟滞0.77%的结果，可应用于智能装置与制程，如新能源车、机器人与航天航空等领域。

Abstract: This experiment validates the application of a quartz resonant force-sensing chip integrated into a tooling gripper. The gripper features stress-concentrating grooves designed to accommodate the chip. Frequency signals from the chip are read by a frequency counter and compared with forces applied via a hydraulic pressure system for calibration. The system demonstrates an overall linearity of 98.7%, repeatability of 95.2%, and hysteresis of 0.77%. It can be applied in smart devices and manufacturing processes across fields such as new energy vehicles, robotics, and aerospace.
