摘　　要：轨道发射器通电轨道要承受很大的电磁扩张力,为了控制发射器口径形变,避免烧蚀,通常要在发射装置的封装层上施加预紧力。针对具体发射装置,运用三维耦合场对不同螺栓预紧力下的口径形变进行了计算,并进行了相关试验。试验结果表明,须将口径形变百分比控制在0.61%以内,方可实现无烧蚀发射。Large electromagnetic force is put on rails of the Rail-Launcher,and the encapsulation of the launcher is always preloaded for caliber control and ablation avoidance.For one launch instrument,the caliber change under different pre-compression with bolt was calculated in 3-D coupling field,based on which some experiments were carried out.The result shows that the launch without ablation could be realized if the caliber change percentage is limited within 0.61%.
