After discussion and annalysis of the unsymmetrical crystal , the geometry description is completed and the simulation of the result has been done . then , it confirms the geometry descprition of unsymmetrical quadrangular crystal and pentagonal crystal 讨论分析端盖量能器不规则晶体结构及其几何实现,并对实现后的机构进行模拟,确定了端盖晶体中不规则四边形晶体及五边形晶体的几何描述。
It is comprised of a sensor head ( a quadrangular pyramid tip , a base , four quartz crystal plates ) and a network analyzer and an apparatus to apply three - axis force . according to mechanics , four plates of the quadrangular pyramid tip correspondingly receive four one - dimension forces when applying a three - axis force to the sensor head . because quartz crystal has a force - frequency effect , namely , resonance frequency change of the quartz crystal is in direct proportion to one - dimension forces applying to it , four certain resonance frequency changes of the four quartz crystal plates are corresponding to a three - axis force 当传感头受三轴力作用时，根据力学的分析可以确定三轴力与四角锥体四个面上单向力之间的对应关系，用分别贴在四角锥体四个面上的四片压电石英晶体作为压敏元件，由于石英晶体的力频效应（即石英晶体在受到应力作用时，它的谐振频率与应力大小成正比） ，从而最终确定了四片石英晶体的谐振频率改变量与传感头上所受三轴力大小和方向之间的对应关系。
