缺口型柔性铰链柔度闭式解的建立与验证方法
Research on the Establishment and Verification Method of the Closed-Form Solution for Notch-Type Flexible Hinges
摘要
Abstract
Although the closed-form solution for the flexibility of existing notch-type flexible hinges is widely recognized and mature,there is little detailed discussion on its establishment process and verification methods.To address the insufficient theoretical calculation references during the design and development of new flexible hinges,this paper elaborates on the process of establishing the closed-form solution for the flexibility of notch-type flexible hinges using the integral method,based on the deformation analysis process and methods of classical material mechanics for constant cross-section beams and variable cross-section beams under linear small deformation conditions.Furthermore,finite element analysis and experimental testing were conducted.The results show that the errors between the closed-form solution and the finite element results,as well as the experimental results,are approximately 7%and 6%,respectively.关键词
