Abstract
The present invention belongs to the technical field of multiple bolt transverse load loosing testers, and relates to a closed loop control method for transverse load amplitude of multiple bolt loosing tester. The closed loop control method is used to conduct stepless amplitude modulation and accurate control for transverse loads of a multiple bolt loosing tester, thereby realizing stepless amplitude modulation and accurate control for the transverse loads. The closed loop control method is realized based on the multiple bolt loosing tester. The multiple bolt loosing tester consists of four parts: a transverse load amplitude control part, a transverse load transmission part, a torque load transmission part and an axial load transmission part. The present invention can provide stepless amplitude modulation continuous transverse loads for a flange bolt set and guarantee the accuracy of the transverse loads through a closed loop control system.
