Problems solved by technology

At this time, the helical gear steering device needs to be installed in the pod bag with a very small space, which will cause the entire structure to be crowded, which is not only inconvenient for installation, but also causes greater processing difficulty, and is also easy to cause the rotation of the pod bag. The heavy weight of the rudder and propulsion device affects the center of gravity and inertia adjustment of the ship model and affects the test effect
Therefore, it is difficult to realize the rudder steering test device of the existing pod propulsion ship model, the structure is too compact, and there are many factors affecting the test, which is not conducive to the test or even difficult to realize the test

Abstract

The invention provides a rudder steering test device for a pod propulsion ship and a mounting method thereof, belonging to the technical field of ship measurement. A rudder steering test device for apod propulsion ship includes a drive support, a rudder steering drive structure, a propulsion drive structure and a control device. As that drive support and the rudder drive structure are incorporatein the present invention, Most of the propulsion drive structure is located on the upper deck of the aft part of the hull, the invention avoids the defect that the propulsion structure is arranged inthe pod bag with narrow space, Easy installation, easier to machine, so that that scheme is easy to realize, the problems of small-scale pod propulsion ship model turning to rudder and propulsion difficult to realize are solved, The invention also avoids the problem of the center of gravity and inertia adjustment of the ship model caused by the excessive weight in the pod bag, eliminates the excessive influence factors, improves the accuracy and reliability of the test, improves the technical level of the hydrodynamic test of the ship model, and provides the installation method of the test device, which can realize the quick disassembly and assembly and improve the test efficiency.

Description

technical field [0001] The invention relates to the technical field of ship measurement, in particular to a rudder steering test device for a pod propelled ship and an installation method thereof. Background technique [0002] In order to ensure the performance of ships, shipbuilding often needs to conduct seakeeping and maneuverability tests of ship models. Due to the need to consider the safety of the test, the ship model for the test is generally small. In the ship model test of combined propulsion with paddle and rudder, the rudder and paddle are independently installed and controlled independently, and the test process is simple and easy to control. However, for a pod-propelled ship, the pod of a small ship model is too small. Since the pod has both functions of rudder and propulsion, it is necessary to realize the joint control of the pod package and the propeller at the same time in the pod package, which is difficult to realize. larger. At present, the traditional ...
