General resistance calculation method for yacht motion mathematical model in yacht simulator

Abstract

The invention discloses a general resistance calculation method for a yacht motion mathematical model in a yacht simulator. The general resistance calculation method comprises the following steps: reading yacht profile data and simplifying a yacht geometric model; dividing a yacht motion volume Fourier number interval; calculating yacht resistance; combining resistance calculation with a yacht simulator. According to theg method, the yacht geometric model is made into the prismatic yacht shape to be simplified, the mathematical expression difficulty of the yacht geometric model is reduced, andtherefore the yacht resistance modeling difficulty and the yacht resistance calculation complexity are reduced, and convenience is provided for yacht resistance modeling and real-time calculation. According to the invention, the yacht resistance is solved in a segmented manner through a yacht motion state dividing method; the problem that an existing resistance algorithm in the simulator is inaccurate in yacht sliding navigation stage resistance calculation and the problem that a flat plate sliding theory is not suitable for the yacht drainage navigation stage are solved, the method can be well applied to engineering application, and the requirement of the yacht simulator for yacht motion mathematical model resistance calculation precision at the present stage is met.

Description

technical field [0001] The invention relates to a yacht simulator, in particular to a general calculation method for resistance of a yacht motion mathematical model in the yacht simulator. Background technique [0002] With the development of our country's economy and the improvement of people's living standards, yachts have gradually entered the field of vision of people's leisure and entertainment, and the yacht industry has also risen rapidly. With the increase in the number of yachts, the demand for yacht drivers is also increasing, and the Maritime Safety Administration has become more stringent in the qualification certification for yacht drivers. In addition, due to the complexity and danger of the sea environment, yacht drivers need to have a solid professional level and the ability to deal with changing situations. In this context, it is particularly important to strengthen the training of yacht drivers. Most of the institutions engaged in yacht driving training u...
