在研发测试数控机床滚动功能部件精度保持性试验台的基础上，设计一套施力机构，通过控制该机构模拟工作台在立式铣削工况下的受力并完成性能参数的动态测试。为模拟作用在工作台上铣削力，建立力学模型，利用力与力矩相等原理推导出施力机构施加的力与铣削力之间的函数关系，根据施力机构工作原理对所得结论进行适当转化；采用“PC+NC ”数控系统体系结构，在基于多轴运动控制卡PMAC的基础上利用VB完成对测试试验台开放式数控系统的程序设计。操作者通过建立的系统界面实现对试验台各功能控制。该试验台在对性能参数的测试过程中，由施力机构模拟铣削力，这不仅保证测试数据的准确性，还可以节约能源。

To design a set of force-applying mechanism, simulate the stresses of workbench in vertical mill-ing process and complete dymatic test of perfomace parameters by controlling the mechanism on the basis of the research of a testing stand of precision preserve of rolling functional components. To establish a mechani-cal model to simulate the milling stresses of workbench, and makes use of the the principle of the force and moment equal to deduce the functional relationships between the force of mechanism applying and the mill-ing force, makes appropriate transformation according to the working principle of force-applying mecha-nism;adopt the “PC+NC” NC system architecture and use VB complete programming of the testing stand open NC system. Operators can achieve the function of testing stand by the established system interface. In the process of the test of perfomace parameters by testing stand, the force-applying mechanism apply milling force which could ensure test data accuracy and also save energy.
