Objective To enhance the reliability of the gun mechanical systems by introducing the theory of reliability enhancement test into its reliability research. Methods At first, the development dynamics of reliability enhancement test and its necessity of application in gun mechanical systems were analyzed. Then based on analysis of theoretical evidence for reliability enhancement test technologies, the research purpose of reliability enhancement test on gun mechanical systems was clarified. Results According to the major failure modes of gun mechanical system, a reliability enhancement test scheme including 7 steps such as analysis of mechanical working principle etc was instituted. The content and function of each step in the scheme were analyzed in detail. Conclusion The research results could provide theoretical support for application of reliability enhancement test in gun mechanical systems.%目的：尝试将可靠性强化试验理论引入其可靠性研究中，提高火炮机械系统的可靠性。方法首先分析可靠性强化试验的发展动态及其应用于机械系统的必要性，而后在对其理论依据进行分析的基础上，明确火炮机械系统可靠性强化试验研究的目的。结果依据火炮机械系统的主要失效模式，制定了包含机械工作原理分析等7个步骤的可靠性强化试验方案，详细分析了各环节的内容及作用。结论研究结果为可靠性强化试验在火炮机械系统中的应用提供一定理论支撑。
