摘要
文中根据模态分析理论,建立了某武器发射平台的模态分析模型,采用ANSYS软件提供的BlockLanczos法,对该武器发射平台的模态进行了计算,得到了该系统的振动动力特性(固有频率、振型),从而为深入研究该系统的振动机理及振动抑制技术提供了理论依据。
Based on the theory of modal analysis, the modal analysis model of a weapon launching platform is established. By the method of Block Lanczos provided by ANSYS, the computations to the weapon launching system are carried out, from which the eigenfrequencies and eigenforms of the system are obtained. The simulation results provide the theoretical basis for the further studies of the vibration mechanism and the technologies of vibration control.
