Pod propelling system testing device

Abstract

The invention provides a pod propelling system testing device which comprises a motor. An output rotary shaft of the motor is fixedly connected with a main shaft, the end of the main shaft is connected with a commutator, output shafts at the two ends of the commutator are fixedly connected with cross shafts respectively fixed with a propeller, thrust and torque sensors used for measuring axial thrust and torque of the propeller are arranged on the cross shafts respectively, the thrust and torque sensors are connected with signal line sliding rings, and the signal line sliding rings transmit values measured by the thrust and torque sensors out. The pod propelling system testing device is suitable for performance study and matching tests of propellers and pods of multiple types, a series of performance of a pod propeller can be forecast more accurately, and the device is of great significance for performance optimization of the pod propeller and ship trials.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a test device for a pod propulsion system. Background technique [0002] The pod propulsion technology appeared for the first time to solve the problem of ships in ice regions. Later, with the gradual improvement of its technology, the advantages of pod propulsion gradually emerged and attracted people's attention. In recent years, its application in large ships and polar ships has gradually increased, but in the research field of pod propulsion, the development speed is relatively slow. At present, the domestic research work is still in the laboratory stage. Due to the large amount of manpower and material resources required to carry out the performance test of the pod propeller, coupled with the immaturity of the test technology and equipment, most of the research in China currently uses numerical simulation methods. The disadvantages of this research method are also obvious. It cannot ...
