摘要：This study is concerned with the development of a novel mechanical decoupling control device. The coupling is a widespread phenomenon in the hydrostatic transmission system. Many researchers have been doing a lot of work to find reasonable decoupling ways in the past. Unlike other decoupling control methods, a novel pure mechanical decoupling control device is developed for the electro-hydraulic dynamic triaxial instrument. This pure mechanical decoupling control device is used to decouple the strong coupling between the axial loading and the radial loading automatically. The structure of the electro-hydraulic dynamic triaxial instrument (including the mechanical decoupling control device) has been introduced. The strong coupling phenomenon between the axial loading subsystem and the radial loading subsystem has been analyzed. The working principle of the mechanical decoupling control device has been presented and the decoupling ability has been studied by simulation. In order to testify the decoupling ability of the mechanical decoupling control device, a series of experiments have been done in the laboratory. The experimental results show that this kind of pure mechanical decoupling control device works pretty well. This practical decoupling device could be adopted in other similar fields. ? 2017 SERSC.
