一种自供电销轴受力检测系统研究
One Kind of Research on A Self-Powered Pin Force Detection System
摘要
Abstract
In order to achieve real-time online for the force detection of the pin shaft between the rocker arm and the connecting frame in the operation of the coal mining machine,a kind of self-powered pin force detection system based on piezoelectric vibration energy harvested are proposed,which not only provides an important basis for the overload protection of the pin,and effectively solves the problem of the frequent replacement of the power supply. The vibration energy produced by the coal mining machine in the working process will be converted into electrical energy effectively,which ensures the long-term effectiveness working of the sensor and wireless strain collection module. Through multiple tests at the scene,the experiments show that,the self-powered performance of testing sys⁃tem is stable. Intercepting 900 s for the analysis of the coal mining machine during the working time,and the maxi⁃mum load of X,Y and Z are respectively 16.261 73 kN、51.321 43 kN、303.939 31 kN. The test results are close to the actual working condition,indicating that a kind of self-powered pin force detection system based on piezoelec⁃tric vibration energy harvested is feasible and accurate in the application of practical engineering testing.关键词
