基于嵌入式控制器的内燃机机油冷却器综合试验控制系统

本文介绍了一种测试内燃机机油冷却器性能的综合试验系统。通过该试验系统可以实现在高压和低压两个不同工况下自动化地测定被试验产品的疲劳寿命、密封性、以及产品在刚度与强度上的可靠性等性能指标。此试验系统采用上、下位机的控制方案,运用嵌入式控制技术、虚拟仪器技术和计算机液压辅助测试(CAT,Computer A ided Testing)技术,完成了试验台的设计和制作,有效地解决了综合各个测试试验给系统设计与实现所带来的复杂性和可靠性等问题。目前,该试验台实际运行表现良好,已达到系统设计要求。

Oil Radiator's Integrative Test Control System Based on Microcontroller Unit

An automobile engine oil radiator's integrative test system(ORITS) has been developed and is introduced in this paper.Mechanical characteristic tests for the oil radiator product such as pressure cycle,static pressure resistance test and leak test can be performed automatically on this test-bed in terms of the ORITS.The ORITS system has adopted the embedded control technology,hydraulic system CAT(Computer Aided Testing) technology,and virtual instrument technology to assure its design targets: operation stability,environment endurance and user friendship.The test-bed was manufactured and put into practical use.The running results showed that the ORITS had fulfilled the design requirements.
