摘　　要：液体静压导轨在超精密机床中有着广泛的应用,其对机床的动态性能有重要的影响,因此要确定导轨的动态特性。本文对所设计的液体静压导轨进行了仿真和实验模态分析,得到了导轨的固有频率,模态阵型及阻尼系数等模态参数,为静压导轨的设计与使用提供参考依据,同时也为全面掌握液体静压导轨的性能与整机建模分析打下了基础。Hydrostatic guideways are widely used and have a great effect on dynamic parameters of ultra-precision machine tools, so dynamic characteristics of gnideway has to be obtained. Simulated and modal analysis of the designed hydrostatic guideway were done and the modal parameters including nature frequency, modal shapes and damping coefficient were obtained, which provided a reference for mastering the characteristics, designing and using the hydrostatic guideway, and laying a foundation for modeling analysis of whole machine.
