某火箭炮高低机三腔缸机液联合仿真研究

高低机三腔缸是某型火箭炮高低随动系统中的作动装置。为了实现对整体高低随动系统的建模与仿真,需对此非标准液压元件进行原理级建模和机液联合仿真,验证所建模型能否实现正常作动过程。根据其工作原理,通过分析动力学方程,并在ADAMS中建立动力学虚拟样机模型,在EASY5中采用原理级建模方式构建液压模型,最终实现机液联合仿真。通过分析仿真结果可知,对三腔缸的原理级建模方法是可行的,液压缸可实现正常作动,各腔内液压变化与实际工况较接近。同时验证了采用ADAMS与EASY5进行机液联合仿真的有效性,为某型火箭炮整体随动系统建模与联合仿真提供参考依据。

Mechanical and Hydraulic Co-Simulation for a Three-Chamber Hydraulic Cylinder of a Rocket Launcher

Three-chamber hydraulic cylinder is the actuating device of balancing machine in high and low servo system of a rocket launcher. In order to complete the modeling and simulation of the whole servo system,the principle-level modeling and the mechanical-hydraulic joint simulation of the non-standard hydraulic components are needed to verify whether the model can realize the normal process. According to its working principle,the dynamic equation was established and the dynamic virtual prototyping model was built in ADAMS. In EASY5,the principle-level modeling method was used to build the model,finally,the mechanical and hydraulic simulation is carried out. By analyzing the simulation results,it can be concluded that the principle of the hydraulic cylinder modeling method is feasible,and the hydraulic cylinder can achieve normal operation.The cavity of the hydraulic pressure changes and the actual working conditions are closer. At the same time,it validates the effectiveness of the joint simulation with ADAMS and EASY5,and provides a reference for modeling and co-simulation of the whole system of a certain rocket launcher.
