The Study of LSM-SA Dynamic Thrust Testing Device in the Gate of River and Main Canal

Abstract

The application of the linear motor is a hot topic in current researching. The dynamic thrust testing is not also an important indicator in the study of linear motor, but also one of the difficulties in the study of linear motor characteristics. The LSM-SA dynamic thrust testing device was researched in the gate of river and main canal. According to compare with the traditional dynamic thrust test, its principle, advantages and disadvantages was illustrated. Some improvements were further made. Meanwhile, the variation of the improved cogging force was analyzed, the curve of the cogging force was made and the LSM-SA testing equipment was designed. Finally, the accuracy of the equipment was verified. It can directly conduct a test of the dynamic thrust. Nowadays, flood protection and disaster prevention has become an urgent task to solve, it is directly related to the country’s economy and people’s lives. The dynamic thrust to control the gate of the river and the main canal was used to prevent disaster. Therefore, the determination of the dynamic thrust becomes particularly important. In order to achieve the system to operate efficiently and accurately, the size of the dynamic thrust must be accurately determined. The device could achieve high accuracy direct drive to ensure the safe and effective operation of the gate of the river and the main canal, develop the water conservancy.
