Embodiment Construction

[0097] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0098] Such as figure 1 As shown: Oξηζ is a translational coordinate system whose origin is fixedly connected to the hull 1, where the opposite direction of the Oξ axis points to the center of the earth, the Oξ axis is the longitudinal axis of the hull 1, and the rotation angle of the hull 1 around the longitudinal axis Oξ is the roll angle φ . The Oxyz coordinate origin is fixedly connected to the intersection of the gyro rotor axis and the outer frame axis, the Oz axis is the rotation axis of the rotor 5, the Oy axis is the rotation axis of the outer frame 3, and the rotation angle of the outer frame 3 around the Oy axis is the precession angle β, the Oxyz coordinate system It can be regarded as a rotating coordinate system relative to Oξηζ.

Abstract

The invention relates to a method for optimizing parameters of a ship stabilization gyroscope. The method comprises the steps of firstly, establishing a rolling motion mathematical model according tobasic parameters of a ship structure and rolling motion, establishing a mathematical model of combined motion of the gyroscope and a ship according to a moment balance equation of a single-frame control moment gyroscope, separately calculating standard deviation values of the rolling angles of the ship during break and work of the stabilization gyroscope, and establishing an expression of the stabilization rate of the ship stabilization gyroscope; secondly, comprehensively considering the stabilization rate, occupied area, overall quality and motor driving energy consumption of the stabilization gyroscope to select an objective function, and constructing a parameter optimization model of the ship stabilization gyroscope according to the size of an installation space of a ship cabin, the supply power of a power system and the constraint conditions of parameters given by the machining process difficulty of a damper; thirdly, taking the original parameters of the stabilization gyroscope as initial values, and solving the parameter optimization model of the ship stabilization gyroscope through an extreme value solution optimization algorithm to obtain the optimal parameter values of the stabilization gyroscope. The method can effectively improve the stabilization effect of the stabilization gyroscope.

Description

technical field [0001] The invention relates to the technical field of ship anti-rolling, and more specifically, relates to a method for optimizing parameters of a ship anti-rolling gyro. Background technique [0002] The ship anti-rolling gyro is a kind of ship anti-rolling device. In recent years, with the development of modern material science, manufacturing technology, control theory and other disciplines, the ship anti-rolling gyro has returned to people's vision, which has aroused the attention and attention of many scholars. Research. Tristan Perez (2009) established a joint mathematical model of anti-rolling gyro and ship, designed a precession state controller, and changed the damping coefficient in the precession state controller through the feedback precession angle to achieve anti-rolling. You Fangjun (2012) established the joint mathematical model of anti-rolling gyro and ship, and conducted simulation analysis for a certain ship type. The Chinese patent appli...
