半机械式半电子式蠕变持久试验机的设计

Design of Half Mechanical and Half Electronic Creep and Stress Rupture Testing Machine

在机械式蠕变持久试验机的下拉杆末端接入载荷传感器,通过PLC与计算机连接实时通信,实现了试验加载砝码力的自动监测和记录,有效防止了加载砝码出错的情况,并且可以在计算机上进行试验结果的追溯查询,提高了试验测试结果的可靠性。设计了机械式蠕变试验机的杠杆自动调平装置和手动卸载/调平,确保了在测试样的安全。

In the half mechanical and half electronic creep and stress rupture testing machine,a load sensor is connected at the end of the lower pull rod of the machine. PLC programmable controller is connected with a computer to realize the real time communication,then,the automatic monitoring and recording of the loading force are realized,which can effectively prevent the error of the weight loading,and the reliability of the test result is improved by the check back of the test result. A lever automatic leveling device and manual unload / leveling of a mechanical creep testing machine are designed to assure the safety of the test.
