本文分析了测力仪结构参数对使用性能的影响,指出了结构参数的选取是测力仪结构设计的一个重要环节;提高测力仪刚度与保证必要的灵敏度是测力仪结构设计中的一对主要矛盾。提出了解决这一矛盾的方法和措施,并在实际中得到了应用。应用对园板式测力仪的力学分析结果,可以设计出高刚度的具有较大灵敏度和较小交叉灵敏度的三向测力仪。 This paper analyzes the influence of structural parameters of dynamometer on performance, and points out that the selection of structural parameters is an important part of dynamometer structural design; improving dynamometer stiffness and ensuring necessary sensitivity is one of the dynamometer structural designs. The main contradiction. The methods and measures to solve this contradiction are proposed and applied in practice. Applying the results of the mechanical analysis of the circular plate dynamometer, it is possible to design a three-dimensional dynamometer with high stiffness and greater sensitivity and smaller cross-sensitivity.
