    摘要:

    將可靠性優(yōu)化設(shè)計(jì)理論、可靠性靈敏度技術(shù)和穩(wěn)健設(shè)計(jì)方法相結(jié)合,討論了具有任意分布參數(shù)的平面連桿機(jī)構(gòu)運(yùn)動(dòng)精度可靠性穩(wěn)健設(shè)計(jì)問(wèn)題，提出了可靠性穩(wěn)健設(shè)計(jì)的數(shù)值計(jì)算方法。在基本隨機(jī)參數(shù)的前四階矩已知的情況下，通過(guò)計(jì)算機(jī)程序可以實(shí)現(xiàn)平面連桿機(jī)構(gòu)的運(yùn)動(dòng)精度可靠性穩(wěn)健優(yōu)化設(shè)計(jì),迅速準(zhǔn)確地得到平面連桿機(jī)構(gòu)的設(shè)計(jì)信息。

    Abstract:

    By combining the reliability-based optimization design theory, the reliability sensitivity technique and the robust design method, the reliability-based robust design for kinematic accuracy of the planar linkage mechanism with arbitrary distribution parameters was discussed extensively. Subsequently, a numerical method for reliability-based robust design was proposed. Under the condition that the first four moments of basic random parameters are available, computer programs based on this model can be used to complete the reliability-based robust design for kinematic accuracy of planar linkage mechanism accurately and quickly. 
