摘　　要：本课题所做的工作：应用国产的电液比例溢流阀实现了对液压式材料试验机的自动卸载过程控制．成功地利用外装液压传感器解决了电液比例阀精度不高的问题．首次将计算机多媒体技术引入材料试验机控制系统．制成了材料力学的拉伸、压缩等项试验多媒体辅助教学系统．编写了多媒体、微机控制、数据处理等软件，并通过了在线调试和运行．The work done in is research program includes using domestic E. H. P overflowvalve to realize the process control of automatic unloading of materials testingmachine and successful use of peripheral hydraulic sensor to solve the low fidelity problem of E. H. P valve. Moreover it is the first time to employ the computermultimedia control technology into the control system of materials testing machine, and turn out computer multimedia-aided teaching system for the ten sion and oppression test of mechanics of materials. The softwares have beencompiled for multimedia, microcomputer control and data process, and havepassed worksite debugging.
