摘要： 为研究膛口制退器制退效率对采用全枪浮动原理的某新型大口径机枪浮动性能的影响，建立了基于浮动原理且考虑土壤和人体影响的某新型大口径机枪的刚柔耦合模型，对含膛口制退器的机枪系统进行动力学仿真并与试验结果进行对比分析，验证了该模型的正确性；获得了某新型大口径机枪实现全枪浮动的膛口装置制退效率的允许取值范围。结果表明，所建立含膛口制退器的实际某新型大口径机枪刚柔耦合模型精确可靠，所设计的膛口制退器实际制退效率为35.9%，其实现全枪浮动的膛口制退器制退效率的理论取值范围为22.5%~50.0%.

Abstract: A rigid-flexible coupling multi-body dynamic model of a new large caliber machine gun based on floating principle is established, in which the influences of soil and human body on machine gun were considered. The dynamics simulation of the machine gun with muzzle brake is conducted, and the simulated results are compared to the experimental results, and the availability of the proposed model is verified. The range of values allowed for the muzzle brake efficiency of machine gun based floating principle is obtained. The study results show that the proposed rigid-flexible coupling multi-body dynamic model including muzzle brake is accurate and reliable, and the efficiency of the designed muzzle brake is 35.9%. The theoretical range of values for the muzzle brake efficiency of machine gun is 22.5~50.0%.
