Analysis of Coupled Vibration in Isolation System for Airborne Optoelectronic Pod
摘要
Abstract
In order to prevent translational aircraft vibratory disturbances from transforming into quality and accuracy of lineofsight(LOS),a passive isolation system was analyzed and developed. For the point that angular vibration transmissibility could not be analyzed with the model of single deG gree of freedom,a mathematical model of two degree of freedom vibration isolation system was estabG lished.The transfer function between translational aircraft vibration and rotational responses of optoeG lectronic pod was derived.The coupled vibration in isolation system with stiffness error ,damping erG ror and unreasonable layout were analyzed.These analyses provided theoretic basis for the design and assembly of the vibration isolation system.Finally,combining engineering practices,the methods to reduce angular vibration from aircraft linear vibration were proposed.reduce angular vibration from aircraft linear vibration were proposed.关键词
