Floating machine capability study of a fixed constraint and secondary recoil type
To study the use of floating technique and some pivotal problem on a large caliber machine gun, the key technology called fixed-point constraint and secondary recoil are analyzed for spring-type floating mechanism. Firstly, a virtual prototype model of machine gun barrel was established. Through comparing with test result, the model was proved to be credible. Afterwards, floating capability and impact on the performance of floating in spring retrogression were analyzed by the established model. The result indicate that the dynamic parameter matching of the floating automatic mechanism is reasonable, the spring floating mechanism has steady capability and can decrease the recoil force obviously. Besides, the machine can actualize steady floating and firing in the case of spring capability retrogression because of adopting the key technology as fixed-point constraint and secondary recoil.
