中文摘要：

针对现有的微纳机构多响应优化设计方法很少考虑设计过程存在的质量损失的实际情况,以细胞注射3自由度柔顺并联微动平台为研究对象,提出一种基于设计过程质量损失视角下的复杂多响应优化设计方法,通过建立以微动平台多方向的铰链柔度为响应变量的模型,在利用响应曲面方法来揭示柔性铰链各设计因子对微动平台多响应柔度的影响规律的基础上,采用设计过程质量损失模型来评估各设计方案的优劣。解决了当仅考虑机构设计技术参数要求而可能出现的难以评判各设计方案的优劣问题,为最终得到满足多响应柔度约束下的最佳优化设计方案提供了新思路,最后通过实例验证了该方法的可行性和有效性。

英文摘要：

In view of the actual situation of rarely considering the quality loss of design process of existing multi response optimization design scheme of micro-nano mechanism,using the cell injection 3-RRR compliant parallel micro motion platform as the research object,a complex multi response optimization design scheme based on the quality loss perspective of design process was put forward,through establishing response variables model with multiple directions hinge flexibility of the micro motion platform,on the basis that the Response Surface Methodology（RSM） was used to reveal the influence law of multiple response flexibility with flexure hinge various design factors on micro motion positioning platform,used the quality loss model of design process to evaluate the pros and cons of each design scheme. The problem that only considering the mechanism design technical parameters requirements it would be hard to evaluate the pros and cons of each design scheme was solved,it provides a new insight for getting the optimal design plan under the restriction of multiple response flexibility finally,and the correctness and validity of the method is verified with an example in the end.
