对机车走行部进行台架加载磨合试验，是考核机车走行部修造质量，逐步取消机车正线试运的重要手段之一．不同的生产规模要求不同类型的试验台，试验台的测控系统也因之有不同的结构形式．模块化结构的多微机系统能较好地适应各种需要，使得主要电路简化为５种模块，各种试验台的测控系统可由不同数量的各种模块拼装起来，具有提高设备可靠性、减少备品库存、便于排除故障等优点，文中介绍了各模块的组成、功能和各块之间的联系方式．
It is one of the important means to check the construction quality of locomotive running department and gradually cancel the locomotive frontline trial operation. Different production scales require different types of test benches, test-bed measurement and control system also has a different structure. Modular structure of the multi-computer system can better adapt to various needs, making the main circuit is simplified to five kinds of modules, a variety of test-bed measurement and control system can be assembled by a different number of various modules, with equipment reliability and reduce spare parts Inventory, easy to troubleshoot the advantages of the article describes the composition of the module, the function and the contact between the various blocks.
