摘要
对变截面柔性板机构的输入输出关系进行了理论分析,得出了一定受力条件下柔性板机构的输出位移。通过有限元仿真分析得出了输出位移,并进行了相应的实验验证,结果表明理论计算结果与仿真结果误差为1.4%,与实验结果的误差为7.5%,证明理论计算方法是有效的。运用理论计算方法分析了柔性板机构的切割半径、最小厚度、曲柄长度、宽度等关键参数对其输出位移的影响,为后续柔性板机构关键参数的优化设计提供了指导,为研究运动范围更大的柔性板机构提供了技术支撑。
The theory between input and output of the tapered flexure plate mechanism was analyzed,and output displacement of the flexure plate mechanism under certain conditions was obtained. The output displacement was also obtained through finite element analysis,and experimental verification was conducted. The results show that the deviation between theory and simulation is 1.4%,and the deviation between theory and experiment is 7.5%,so the theoretical calculation of it is feasible.The effect of cutting radius,minimum thickness,crank length and width on the output displacement of flexure plate mechanism was also analyzed through theoretical calculation. it provides guidance for design optimization of the key parameters,and also provides technical support for studying the flexure plate mechanism of larger displacement.
