Patent number: 10746642Abstract: A closed-loop control method based on a testing machine for accurately controlling the loosening of a bolt transverse load is disclosed. The testing machine for accurately controlling the loosening of the transverse load comprises a load generating motor, a load transfer mechanism, a load control motor and a load control mechanism. The control method of the present invention controls the load generating motor to drive the load transfer mechanism based on control commands, displacement signals collected by the displacement sensor and force signals collected by an S-shaped column type pressure sensor. The testing machine for the looseness of the bolt transverse load is essential in the aspect of exploring a looseness law of a bolt, and can be used to simulate load bearing conditions of the bolt. However, under the condition that some bolts bear constant force load transversely, the testing machine is not used or is inaccurate.Type: GrantFiled: September 8, 2017Date of Patent: August 18, 2020Assignee: Dalian University of TechnologyInventors: Qingchao Sun, Bao Zhang, Chuanhua Wang, Wei Sun, Yue Ma
