Random Vibration Response Analysis of Loitering Attack Missile Imaging Infrared Seeker
摘要
Abstract
According to the theory of elasticity, modal analysis and random vibration analysis based on the loitering attack missile imaging infrared seeker were carried out. The FEA model of the seeker was established with ANSYS WORKbench finite element software. Computations of modal analysis and random vibration analysis to the seeker were carried out, from which the first six order natural frequencies, main vibration mode, acceleration response and stress response can be obtained. Points of the infrared detector and electronic cabin were taken as monitoring points for acceleration response. Stress response analysis of the seeker was also done according to the given power spectrum density of random vibration. The calculation results show that natural frequency of the seeker was designed reasonably and the acceleration response can satisfy the use requirement.关键词
