中文摘要：

为得到清晰的0—1拓扑分布结构，在SIMP（solid isotropic microstructures with penalization）和SRV（the sum of the reciprocal variables）方法的基础上提出了一种新的混合方法——SIMP-SRV方法，该方法将SIMP得到的优化结果用来初始化SRV方法的设计变量，再用SRV方法得到最终的优化目标。将SIMP—SRV方法应用于柔性机构的0—1拓扑优化设计中，得到了轮廓清晰的拓扑分布结构，完全消除了中间密度单元，从而证明了该方法的有效性。

英文摘要：

Clear-cut 0-1 solutions are often sought. A new hybrid method SIMP-SRV was presented herein based on SIMP and SRV approaches： first, the standard SIMP was employed to generate an intermediate optimal design solutions second, initializing the design variables with the last stage＇s results,SRV approach was adopted to produce the final solution. It is successful to apply SIMP -SRV in the topological design of compliant mechanism. According to the results, sharp 0- 1 solutions are obtained and intermediate density elements are disappear. And the method turned out to be very effective for 0-1 topological design of complaint mechanisms.
