摘　　要：目的研究环境作用动力学及其在武器装备定寿延寿中的应用。方法修正蠕变动力学并提出环境作用动力学,应用环境作用动力学,先期获得武器装备材料和零部件的老化、损伤函数通解,通过短暂的自然环境试验和加速试验数据,确定老化、损伤函数通解的待定系数,外推完成武器装备定寿延寿。结果提出了环境作用动力学,并应用于尾翼弹簧和压缩橡胶密封圈的寿命评估。结论环境作用动力学可以广泛应用于武器装备材料、零部件的定寿延寿领域,为整机、整弹的定寿延寿提供基础支撑。Objective To put forward the theory of dynamics of environmental effect and its application in determination and extension of weapon service life. Methods Dynamics of environmental effect was modified from creep dynamics; common solutions of weathering and damage function of the military material and parts were obtained using dynamics of environmental effect; the parameters of the common solutions were determined using short-term natural environmental test and accelerated test; the weapon service life was determined and extended by extrapolation. Results The theory of dynamics of environmental effect was proposed; the theory was applied in service life evaluation of empennage spring and pressed rubber seal ring. Conclusion The theory of dynamics of environmental effect can be widely applied in determination and extension of service life of weapon material and parts,and provides basic support for the determination and extension of service life of the whole equipment or ammunitiont.
