摘要

摘要: 在柔顺机构优化中如何考虑设计变量的随机波动与外界随机载荷的不确定性干扰成为柔性机构稳健可靠性保障的关键问题。引入6σ稳健设计方法，建立了稳定性优化模型，并对以柔性悬臂梁为载体的柔顺机构进行了柔度稳健优化设计，通过与传统柔性悬臂梁柔度确定性优化结果对比表明，其柔度稳健水平达到了8σ，验证了6σ稳健优化设计具有良好的效果。

Abstract: The fluctuations in random design and the uncertainty from environment play essential roles in the security of robust reliability of compliant mechanisms, especially in how to optimize the compliant mechanism. In present study, a 6σ robust design optimization method is proposed as well as the model of stability and optimizing design. The compliant mechanism was optimized from flexibility and steady, in present paper, which was a carrier of flexible cantilever beam. Compared with the traditional deterministic optimization of flexible cantilever beam, the new method could obtain the 8σ level of flexibility robustness. As it shows that the 6σ robust design optimization method could acquire a favorable effect.
