中文摘要：

柔顺机构柔度稳健性是柔性机构在微机电系统与精密工程等领域广泛应用的前提和基础,但在实际工程中传统设计方法未充分考虑其稳健性.引入田口稳健优化设计方法,选取柔性铰链各结构参数为可控因素,工作载荷为噪声因子,通过正交试验数据分析得出各个可控因素的信噪比和贡献率,进而选出最佳的参数水平组合,并对柔度综合稳健性能的最优方案进行了验证.算例表明,采用田口稳健优化设计的柔性铰链柔度稳健性比传统方法信噪比水平提高了4.68dB,降低了其质量损失,实现了柔性铰链柔度稳定性优化.田口稳健优化设计方法具有普适性,在实际工程应用中具有较高参考价值.

英文摘要：

The flexibility robustness of compliant mechanism is the premise of compliant mechanism widely applying in miniature electromechanical systems and precise engineering field. In practice, this problem cannot be solved by using traditional method. A new robust design method was presented, the structural parameters of flexure hinge and working load were selected as well. By processing and analyzing test data resulted from orthogonal test, the best combination of parameters was obtained and verified by experiment. The results demonstrated that, against the traditional design, the signal noise ratio increased about 4. 68 dB, the quantity loss of flexible hinge reduced. It also implemented the flexibility stability optimization on the flexible hinge. Finally, the flexibility robustness of flexible hinge could be optimized. The robust design can be widely used and has reference value in application.
