摘要
论述了试验台2000kN、600kN二等标准测力机的技术改造和取得的效果。改造时采用可编程序控制器(PLC)作为测力机的控制核心,配套设计安装了控制柜和驱动程序等。对机械部分也进行了改造,更换了损坏的设备,经调试满足试验要求。经近30次试验没出现质量和安全问题,达到了改造目的,保证了试验数据的准确和真实,提高了两台测力机的可靠性。
Improvements of the 2000kN and 600kN dynamometers of 1# and 2# test stands were described in the paper. In the improvement, the PLC is used as heart of the dynamometer, the control and the control cabinet and diving programs have been installed. The mechanical part is also improved by the changing of damaged equipments. 30 tests without any quality and safety problems have demonstrated that the improvements are successful and the reliability of the dynamometer has been improved.
