Paper Abstract

The focus of this paper is to investigate an accurate deflection angle distribution on the key portion for the bent focusing mirror subassembly in nonlinear analysis. Bent focusing mirror system is the heart of the Shanghai Light Source beam-line, which can realize beam deflecting, collimating and focusing .Big errors were existed in the past of using linear method analyzing nonlinear parts for bent focusing mirror subassembly. In test of the system, there is a phenomenon of the rod that is prized, and the linear analysis results don't conform to the test result. It is concluded that there is friction between rod and sleeve, which result in the phenomenon of prized rod. To solve the problem, the contact and nonlinear analysis method are introduced in this paper. After summarized the main factors for structural nonlinearity, a concrete contact nonlinear analysis of bent focusing mirror subassembly is given. A comparison in the bent focusing mirror subassembly by nonlinear and linear analysis is carried out. The results indicate that contact nonlinear analysis is more accurate than linear analysis and closer to real system in engineering analysis of bent focusing mirror subassembly. The mirror distortion result under given temperature load is also given.
