滚动直线导轨副综合试验台加载系统优化设计

摘要

Considering the characteristics of the test project of rolling linear guide comprehensive test rig, The paper compared the common four kinds of load systems to choose the best one,and then designed the hydraulic loading system,analysed and optimized the portal frame with the finite element analysis method. As a result,it designed a loading system suitable for comprehensive test of the rolling linear guide.%针对滚动直线导轨副综合试验台加载的需求，通过对比分析选择出最佳加载方式，然后对液压加载系统进行设计，并对加载系统中的关键部件龙门架进行有限元分析和优化设计，设计出一套适合于滚动直线导轨副综合性能测试试验台的加载系统。
