[摘要] 通过对参数灵敏度分析提出形质灵敏度、频质灵敏度新概念,大量工程结构分析表明采用形质灵敏度用
于结构性能优化更有效率,导出若已知目标控制量可得到变量允许改变量,对产品变型设计、零件公差设计、
产品装配调试具有指导意义。针对机械压力机精度调试过程对参数灵敏度应用方法进行说明,通过对比压力机
左右不同步偏差与参数灵敏度曲线,快速发现问题所在,经过修正后压力机精度得到很大提高。

[Abstract] Through the analysis of parameter sensitivity of the new concept of quality sensitivity, analysis
shows that the morphological structure sensitivity for performance optimization more efficient large
engineering structure, export control objectives can be obtained if the known variables are allowed to change
the quantity, of product variant design, part tolerance design, product assembly debugging has guiding
significance. According to the mechanical precision of press debugging process description of parameter
sensitivity method, paring the press about not synchronous error and parameter sensitivity curve,
quickly found the problem, the revised press precision has been improved.
[Keyword] Sensitivity; Morphometric sensitivity; Frequency mass sensitivity;Synchronization.
