Structural dynamics modification with targets of random responses for a vibration system is a complex and practical problem. 針對(duì)振動(dòng)系統(tǒng)在隨機(jī)激勵(lì)下的響應(yīng)進(jìn)行結(jié)構(gòu)動(dòng)力修改是具有實(shí)用價(jià)值的工程問(wèn)題。
This paper put forward an improvement on the method for structural dynamics modification based on the sensitivity analysis to use it in the practice. 針對(duì)基于靈敏度分析的結(jié)構(gòu)動(dòng)力修改方法在實(shí)際應(yīng)用中的不足之處，改進(jìn)了用于計(jì)算的公式，使之能夠直接指導(dǎo)工程實(shí)踐。
Structural dynamics modification of car front-body subsystem is crucial to the laboratory road simulation test in which it is used for testing instead of car body. 對(duì)轎車車頭子系統(tǒng)進(jìn)行正確的結(jié)構(gòu)動(dòng)力修改是利用其代替整車進(jìn)行室內(nèi)道路模擬試驗(yàn)的關(guān)鍵。
