摘　　要：以某惯导平台系统为研究对象,基于符号动力学理论对该系统中的振动平台进行数学建模,并求解其冲击响应。将该冲击响应作为边界条件,利用ABAQUS软件分析该系统中惯导设备的抗性冲击性能,包括基于模态的振动响应分析和基于时间历程的冲击响应分析2部分。在此基础上,提出一种基于符号动力学的惯导平台系统抗冲击性能分析方法,同时验证该系统具有良好的抗冲击性能。研究表明:该方法能有效实现对惯导平台系统冲击响应的快速评估,提高分析求解效率,并对系统薄弱环节的抗冲击性能进行全面剖析。Taking a certain inertial navigation platform system as the research object,a mathematical model of the vibration platform in the system is established based on the theory of symbolic dynamics,and its impact response is solved.Using the impact response as a boundary condition,ABAQUS is used to analyze the impact resistance performance of the inertial navigation equipment in the system,including modal based vibration response analysis and time history based impact response analysis.By summarizing and analyzing the process,a method for analyzing the impact resistance performance of the inertial navigation platform system based on symbolic dynamics is proposed,and it is verified that the system has good impact resistance performance.Research has shown that this method is beneficial for achieving rapid evaluation of the impact response of inertial navigation platform systems,improving analysis and solving efficiency,and comprehensively analyzing the impact resistance performance of weak links in the system.
