Characteristics Analysis of High Speed andHigh Frequency Steering Gear of Ship

In order to provide theoretical basis and technical support for high-speed high-frequency ship steering gear design, a new method based on ADAMS, SIMULINK and AMESim co-simulation analysis is put forward, the relationship between the dynamic characteristics of system and subsystem unit, nonlinear factors is analyzed in the article. Co-simulation model of ship steering gear based on ADAMS, SIMULINK and AMESim is built. From the perspective of time-frequency to research the effect of the subsystem characteristics including variable pumps, control systems, feedback mechanism sensor, and the nonlinear factors including space, the dead zone, disclosure sensitivity, on system frequency response characteristic of steering gear, as well as the relationship and rules. Then acquired the general guidelines for high-speed high-frequency steering gear design.
