本文利用動(dòng)態(tài)實(shí)驗(yàn)分析和理論模型分析兩種方法對(duì)臥式加工中心的動(dòng)態(tài)性能進(jìn)行了分析，通過(guò)實(shí)驗(yàn)測(cè)試數(shù)據(jù)與理論計(jì)算結(jié)果對(duì)比分析，驗(yàn)證了理論模型的合理性，找出了機(jī)床的薄弱環(huán)節(jié),并進(jìn)行了結(jié)構(gòu)優(yōu)化。優(yōu)化后分析結(jié)果證明，機(jī)床結(jié)構(gòu)的最大變形值都相應(yīng)地低。

Abstract：This paper introduced Dynamic Experimental Analysis and Theoretical Model Analysis ananalyzed the dynamic characteristics of Horizontal Machine Center, by comparing the? data obtained from? experimental to theoretical calculation result, the Theoretical Mode was rational, finded out the weak position of machine tools，and optimized its structure. analysis result showed, the data of maximum deformation is accordingly lowed.
