    摘要:

    激光系统光学负载易受平台振动的影响,对其光束控制和高精度捕获跟瞄造成严重的技术困难。本文针对复杂动态环境下激光系统“看不见”、“稳不住”和“打不准”等问题,设计了适用于大型光学负载的高减振致稳平台;基于磁流变弹性体优越的变阻尼性能,设计了三自由度磁流变隔振装置,并开展了磁流变阻尼器的结构设计;基于理论分析和有限元计算方法,使用Matlab软件开发了振动系统动力学仿真程序,研究并验证了隔振装置的隔振缓冲性能。仿真结果表明,本文设计的高减振致稳平台满足光学平台及上装设备的减振缓冲要求,具有良好的隔振缓冲性能,可以解决大型光学负载动平台机动跟瞄的关键问题,提升激光系统动态光束控制和高精度捕获跟瞄能力。

    Abstract:

    The optical load of the laser system is susceptible to the vibration of the platform, which causes serious technical difficulties in beam control and high-precision acquisition and tracking. In this paper, aiming at the problems of " invisible ", " unstable " and " inaccurate " of laser system in complex dynamic environment, a high vibration reduction and stabilization platform suitable for large optical load was designed. Based on the superior variable damping performance of magnetorheological elastomer, a three-degree-of-freedom magnetorheological vibration isolation device was designed, and the structural design of magnetorheological damper was carried out. Based on the theoretical analysis and finite element calculation method, the vibration system dynamics simulation program was developed by using Matlab software, and the vibration isolation and buffering performance of the vibration isolation device was studied and verified. The simulation results show that the high vibration reduction and stabilization platform designed in this paper meets the requirements of vibration reduction and buffering of optical platform and upper equipment, and has good vibration isolation and buffering performance. It can solve the key problem of maneuvering tracking and aiming of large optical load, and improve the dynamic beam control and high-precision acquisition and tracking ability of laser system.
