摘　　要：为了提高操舵系统可靠性和安静性,以新型电液操舵装置为对象,将装置启停过程精细地分为三个阶段,建立了这三个阶段的液压冲击数学模型。基于数学模型,提出了减小启动阶段液压冲击的“快-快-慢”装置运行控制方法和减小停止阶段液压冲击的“慢-快-快”装置运行控制方法,仿真验证两种控制方法正确有效,可有效降低装置启停过程中的液压冲击。To improve the reliability and quietness of steering system,the electro-hydraulic steering gear was taken as the research object,and the starting and stopping process of the steering gear was elaborately divided into three steps,of which the hydraulic shock mathematical models are established respectively.Based on the mathematical models,a"fast-fast-slow"steering gear operation control method for the starting and"slow-fast-fast"steering gear operation control method for stopping process was proposed to reduce the hydraulic shock,and then verified by simulation,which is of great significance to the reduction of the ship steering hydraulic shock.
