摘要
为避免在发射过程中高频射击工作载荷引起火炮结构剧烈振动,提高车载高炮射击精度,对某车载高炮火力系统模态分析进行研究。建立高炮火力系统结构拓扑关系和有限元分析模型,采用ANSYS Workbench软件对其进行模态分析,得到火力系统俯仰部分的固有频率和振型,并通过模态试验对有限元模态计算结果进行验证。验证结果表明,该研究可为车载高炮火力系统的动力学分析和结构优化设计提供依据。
In order to avoid high frequency shooting load causes the trucked anti-aircraft gun’s structure vibrates violently during the launch process and to improve the anti-aircraft gun’s firing accuracy,research the modal analysis of trucked anti-aircraft gun fire system.Establish the structure topology and finite element analysis model of the anti-aircraft gun fire system,using the modal analysis in ANYSYS Workbench software to obtain the fire system’s natural frequency and vibration mode.The finite element modal calculation results are verified by modal test.Verification results show that this research can provide the reference for the dynamic analysis and structure optimization design of the anti-aircraft gun fire system.
