The project takes construction of the high resolution earth observation system as its background. The remote sensing satellites are always multi-physical field coupled. The method of multi-profession integrated design and optimization is explored for development of the very high resolution satellites. To solve the multi-field coupling problem in the satellites design, a coupled multi-field analysis model is established based on the study of correlating coupled field model. On the basis, a progressive optimization method based on multidisciplinary investigation design is proposed for the use of optimizing the whole satellites structure. For vibration reduction in structure design of the remote sensing satellites, the vibration reduction analysis method of NES with the external-exciting force is studied at first. The design method based on NES for satellites shock absorber system is proposed, and the shock absorber system is designed. On the basis of the above study, in the case of coupled dynamical disturbances of the remote sensing satellites in space environment, a dynamical model of the satellite system is proposed based on transfer path analysis method, and then a set of analysis methods on the transfer characteristics of multi-disturbances in the satellite system are studied. The method of integrated thermal structural electromagnetic and force limited optimization design of a satellite structure is proposed when we take the coupled static and dynamic problem brought up by the space temperature environment and the multi-disturbances into account. The aims of this project are to format a set of complete theory on the multi-profession integrated design and to provide theoretical basis and research platform for the optimization of high resolution remote sensing satellites.
