Posture adjusting mechanism for pod dynamometer

Abstract

The invention discloses a posture adjusting mechanism for a pod dynamometer. The mechanism comprises a flange, a rotation posture adjusting mechanism is installed at the bottom of the flange, a through hole is formed in the middle of the rotation posture adjusting mechanism, a supporting rod inner shaft of the pod dynamometer is installed concentric with the through hole, a transition plate is fixed to the bottom of the rotation posture adjusting mechanism through a fastener, a six-component balance is installed at the bottom of the transition plate, a trim posture adjusting mechanism is installed at the bottom of the six-component balance, and an inner shaft of a supporting rod of the pod dynamometer penetrates through the middle of the six-component balance and the middle of the trim posture adjusting mechanism at the same time. Through cooperative work of the trim posture adjusting mechanism and the rotation postureadjusting mechanism, comprehensive adjusting means and high adjusting precision can be achieved, the yaw angle of the pod dynamometer can be automatically adjusted, the adjusting precision is extremely high, fine adjustment of the trim angle of the pod dynamometer is achieved, adjustment of each degree of freedom is simple and convenient, and mutual coupling is avoided.

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...
