摘　　要：支腿与轮胎是混合支撑的承重件,目前已认识到混合支撑是能够满足导弹稳定发射条件,但对该两种承力件的载荷分配对导弹发射影响特性并不明确,为研究支腿、轮胎载荷分配比对导弹发射过程的影响,运用有限元软件ABAQUS建立了简化的车载导弹系统模型,通过对3种具有代表性的支腿、轮胎载荷分配比进行计算并加以比较。分析结果表明,不同载荷分配比对导弹发射过程有一定的影响,为导弹混合支撑载荷分配比的选择提供了依据。Leg and tire are the main bearing structures of mixed support,at present,the fact that mixed support can satisfied with conditions of missile stabilization launch.It is now recognized that mixed support can meet the stable launch conditions of missile.But it is not clear that the load distribution of the two kinds of load-bearing units is different.To study on the influence of leg and tire load distribution based on the mixed support of the missile launch stability.Using ABAQUS which is the finite element analysis software to establish a simplified model of the vehicular missile launcher.Dynamic simulation for three representative rate of load distribution.The simulation results show that different load distribution compares the impact of the missile lunch trajectory,provide the basis of the selection of load distribution on the mixed support.
