STRESS ANALYSIS AND STRUCTURE DESIGN OF THE MULTI-RING INTERMIXING COMPOSITE FLYWHEEL
摘要
Abstract
Based on plane stress full elastical model,a plane stress analysis model of the multi-ring intermixing composite flywheel is forwarded by considering the anisotropy of filament winding composites.2D axisymmetric FEM is used to verify the validity of this model.The former plane stress analysis model is used to find out the quantitative relationship between the stress distribution of the rotor and these factors such as the different modulus ratio of rotor material,the quantities of rings,the thickness ratio of rings,the interference between rings on static or roating speed.The results show that the stress and strength distribution can be improved when the greatest modulus ratio of outermost or the radial thickness of outermost rings or the interference between hub and inner ring are increased in the multi-ring intermixing composite flywheel.Based on the former result,a three-ring intermixing composite flywheel with high energy density is designed by glass fibre,T700,and T800.3D FEM is used to verify the validity of this structure.关键词
