A pod dynamic instrument attitude adjustment mechanism

Abstract

A pod dynamometer attitude adjustment mechanism includes a flange, a rotary attitude adjustment mechanism is installed at the bottom of the flange, a through hole is arranged in the middle of the rotation attitude adjustment mechanism, and a pod dynamometer is installed concentrically with the through hole. The inner shaft of the support rod, the bottom of the rotary attitude adjustment mechanism is fixed with a transition plate through fasteners, the bottom of the transition plate is installed with a six-component force balance, and the bottom of the six-component force balance is installed with a trim attitude adjustment mechanism , the inner shaft of the strut of the pod dynamometer passes through the middle of the six-component force balance and the trim attitude adjustment mechanism at the same time. Through the cooperation of the trim attitude adjustment mechanism and the rotation attitude adjustment mechanism, comprehensive adjustment methods and high adjustment accuracy can be achieved, which not only realizes the automatic adjustment of the yaw angle of the pod dynamometer, but also has extremely high adjustment. Accuracy is achieved, and the fine adjustment of the pitch angle of the pod dynamometer is realized. The adjustment of each degree of freedom is simple and convenient, and there is no mutual coupling.

Description

technical field [0001] The invention relates to the technical field of ship dynamics test equipment, in particular to an attitude adjustment mechanism of a pod dynamometer, in particular to the automatic fine adjustment of the yaw angle and the precise adjustment of the pitch angle of the pod dynamometer. Background technique [0002] With its superior hydrodynamic performance and reliable installation method, the pod propeller has gradually been applied on various ship types all over the world. [0003] At present, the optimization test for the initial yaw angle of the pod propeller has become an important part of the rapid model test of the pod propulsion. The hydrodynamic measurement of the pod dynamic instrument at different attitude angles (including yaw angle and pitch angle) can obtain the energy-saving effect at different attitude angles, and provide technical support for determining the initial installation angle of the pod propeller. [0004] In the pool laborator...
