基于AMESim-Simulink的拨叉式液压舵机系统仿真研究
|
摘要
针对拨叉式液压舵机系统,运用AMESim软件建立舵机液压系统模型和Simulink软件建立舵机转舵扭矩模型,联合二者对转舵力矩和液压缸压差进行了仿真分析,结果表明:转舵力矩和液压缸压差随着舵角的增加而增加,转舵力矩在大舵角区时受航速和吃水影响较大,液压缸压差在小舵角区受到航速和吃水的影响较小。
The fork-type hydraulic steering gear system is taken as a research object. The hydraulic system model of steering gear was established with AMESim software and the torque model of steering gear was established with Simulink software, and the steering torque and hydraulic cylinder pressure difference were analyzed in the co-simulation. The results show that the steering torque and the hydraulic cylinder pressure increase with the rudder angle, the steering torque is more influenced by the ship speed and draft when rudder angle is in the large area, and the hydraulic cylinder pressure is less affected by the ship speed and draft when rudder angle is in the small area.
