| Abstract: |
| 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. |
