摘要
本文主要研究磁流变阻尼器应用在高速、高冲击性环境下发射装置的反后坐装置中,其结构参数磁感应强度和阻尼通道间隙对发射装置的振动影响;采用有限元和abaqus软件二次开发平台相结合的方法建立该发射装置结构动力学有限元模型,改变磁流变阻尼器的结构参数模拟整个装置的发射过程,研究发射装置的振动特性。仿真计算结果表明,输入不同的电流值和不同的阻尼通道间隙值会对发射装置振动特性产生影响,在设计和应用发射装置上磁流变阻尼器时应给予重视。
This paper mainly studied the influence of magnetic induction and damping channel clearance, which is used in the recoil device of a launcher working in a high speed and high impact environment. Finite element method and the secondary program development platform in ABAQUS were combined to establish the structural dynamic finite element model of the launcher. The launch process of the whole device was simulated by changing the structural parameters of MR dampers, and the vibration characteristics of the launcher were obtained. The simulation results show that the different value of the input current and the gap of different damping channel could influence the characteristics of the launcher, and attention should be paid to the design and application of MR damper on the launcher.
