基于柔性铰链的传动及导向原理,提出了一种可以精确的放大直线位移的微型机构,该机构具有对称性好、机构简单紧凑、无附加位移、位移放大精度高等优点;在建立该机构的运动学模型基础上,给出了其工作原理;根据机构学原理计算出该机构放大比例,采用有限元法对该机构进行静力学分析,二者误差为4.66%。 Based on the principle of transmission and guide of flexible hinge, a micro-mechanism capable of accurately amplifying linear displacement is proposed. The mechanism has the advantages of good symmetry, simple and compact structure, no additional displacement and high precision of displacement amplification. After establishing the movement of the mechanism Based on the learning model, the working principle is given. According to the mechanism principle, the magnification ratio of this mechanism is calculated, and the static analysis of the mechanism is carried out by the finite element method. The error between them is 4.66%.
