结合工程实践 ,为增加精密机床的基础刚度 ,采用钢桁架 -混凝土组合结构。分析计算和试验结果表明 ,根据弹性理论得到的这种新型组合结构的计算结果能够满足工程应用的要求。
Combined with engineering practice, in order to increase the basic stiffness of the precision machine tool, a steel truss-concrete composite structure is adopted. Analysis and calculation and test results show that the new composite structure obtained from the elastic theory can meet the requirements of engineering application.
