本文介绍了机油泵耐久性试验微机控制系统,重点介绍了耐久性试验特有的程序加载方法和在载荷曲线基础上进一步模拟实际运行所采取的措施。同时还介绍了系统运行必须采取的防干扰措施。实践表明,利用微机控制耐久性试验,不仅能完成人工无法胜任的实时操作,使试验更精确、可靠,而且有可能以实际载荷谱为依据,从而获得更确切、可靠的数据。 This article introduces the microcomputer control system of the durability test of the oil pump, emphasizes the procedure loading method which is unique to the durability test and the measures taken to further simulate the actual operation based on the load curve. At the same time also introduced the system must take anti-interference measures. Practice shows that the use of microcomputer-controlled durability test not only can not be done manually in real-time operation to make the test more accurate and reliable, and may be based on the actual load spectrum to obtain more accurate and reliable data.
