NUMERICAL ANALYSES OF DESIGN AND ASSEMBLY FOR MAIN COMPONENTS OF BESIII

The design and manufacture of the main drift chamber(MDC)and the electro-magnetic calorimeter are most important issues in Beijing electron-positron collider upgraded projects.The whole mass of electro-magnetic calorimeter(EMC)in BESIII is 40t,thus high stiffness,strength and dynamical properties are required for the design of entire structural of electro-magnetic calorimeter. Based on numerical technique,the strength and the dynamical properties of EMC are analyzed, which provide theoretical reference f...
