| 摘 要： | 柔性铰链四杆机构在精密机械中的应用日益广泛。采用伪刚体模型法对具有集中柔度的全柔性铰链四杆机构进行了分析,得出了外载荷与转角的一般计算公式。给出了计算实例,并与有限元软件ANSYS仿真结果进行了对比,误差在3%左右,验证了该分析方法的有效性。最后也得出了外载荷与危险点应力成正比的关系。

| Abstract: | Four-bar flexure hinge mechanisms are used widely in the precise machine day by day.A four-bar flexure hinge mechanism with pseudo-rigid-body model is analyzed in this paper,the relationship between loads and the angular deflection is obtained.An example is given,and contrasted with the simulation results of the ANSYS finite elelent software,the error is about 3%,so it proves the validity of the anlysis.Finally,the proportional relationship between loads and the stress of the danger point is also educed. |
