摘要
针对多管火箭系统多领域系统仿真的难题,推导了在Matlab/Simulink中液压高低机构的数学模型,以及ADAMS-Matlab协同仿真手段机液耦合虚拟样机的建立过程。通过仿真,分析了某多管火箭系统采用液压高低机构的发射动态特性,验证了多领域协同仿真方法的有效性,同时表明采用液压高低机构能够满足多管火箭系统设计要求。
It is difficult to do multi-field co-simulation of a multiple launch rocket system （MLRS）. Therefore, we induce the mathematical model of an elevating hydraulic machine in Matlab/Simulink and the establishment process of a machine-liquid coupling system co-simulated by ADAMS and Matlab. Through the co-simulation, we analyze the dynamic characteristics of the MLRS during its launch using the elevating hydraulic machine and verify the effectiveness of the multi-field co-simulation method. The analysis results show that the elevating hydraulic machine can meet the requirement of MLRS design.
