摘要
自行火炮输弹机液压系统的动态数学模型,基于自行火炮液压系统输弹机结构和工作原理,采用功率键合图的建模方法建立。由该模型推导出系统的状态方程,并用Matlab-Simulink,先设置约束条件,再对其进行动态特性仿真,其结果和实际情况相符合。仿真结果能为液压系统的检测和诊断提供依据。
Based on the laboring structure and working elements of the ammunition handling of the self-propelled artillery, the dynamic mathematical model of the hydraulic system for self-propelled artillery was established by means of power bond graph. The model deduced the system, then set the restriction conditions and simulated the system dynamic characteristics based on Matlab-Simulink. The simulation results matched the face. The results could provide a foundation for the detection and diagnosis of the hydraulic system.
