摘　　要：针对导弹倾斜热发射碰撞安全性问题,本文研究了发射箱箱口下沉量规律计算和分析方法。通过力学分析和达朗贝尔原理,推导了发射系统受力模型,并且获得了箱口负载计算模型和计算方法。通过算例,计算分析了导弹出箱过程的负载力矩,包括重力负载和摩擦力负载,并与实测箱口下沉时域曲线进行了对比。研究发现箱口负载计算曲线与下沉实测曲线规律基本一致,从而验证了本文分析方法的可行性。本文方法对导弹发射过程的箱口下沉量计算有较强的参考意义。To solve the launch safety of the missile, the subsidence’ disciplinarian of the launch container during oblique-launch process of missile is investigated. Using mechanics analysis and Dalembert principle, the oblique-launch dynamics model is put forward, where the mechanics model and the calculate method of the container is derived. At last, during the launch process, the load torque of the missile is studied by example, where the load of the weight and the fraction are studied. It is found that the calculation result is as the same as the test one. The method is verified and has very big reference on the subsidence calculation of the launch container during oblique-launch process.
