摘　　要：通过研究分析弹(箭)结构热强度力热联合试验顶压式加载的实现策略及方法,完成了加载方法的实施、控制策略的优化,安全保护脚本程序的编制。通过在地面模拟力热载荷耦合的飞行环境,设计并进行了级联顶压式力热联合加载、多点力热联合加载的复合试验,获得了安全稳定的力热控制全程加载。The present work is devoted to study the achievement strategy and method of jacking pressing loading in thermal-mechanical testing for structures of projectiles and rockets. The implementation of loading, the optimization of control, and the compiling of script program for safety are accomplished. By simulating the mechanical-thermal coupled loading flight environment on the ground, we design and conduct the cascade jacking pressing loading and the multi-point loading mechanical-thermal combined tests, and obtain safe and steady loading history.
