Winding CFRP grinding wheels exhibited high circumferential strength but relatively low radial strength，and are prone to interlaminar delamination，which limits their performance.A multi-ring interference fit assembly can effectively enhanced the radial strength of grinding wheels.In this study， an analytical model was established via theoretical analysis to guide the selection of interference fit for anisotropic wheels.Using finite element modeling and deformation measurement experiments，it analyzed the effects of different parameters（interference fit amount，individual ring thickness，and number of assembled rings） on the structural performance of multi-ring interference fit assembled winding grinding wheels with dimensions Φ360 mm×120 mm×16 mm.The results indicate that increasing the number of assembly rings leads to a more uniform stress distribution and reduces the risk of debonding between rings.Decreasing the thickness of each ring raises the radial stress it sustains and reduce the risk of delamination；when ring thickness is graded to increase progressively from the inner to the outer ring，the total deformation is minimized and overall performance improves.The allocation of interference fit between any given pair of adjacent rings has little effect on the stress levels in the other rings；for the pair itself， larger interference fit reduces the tendency to delaminate.By tuning the interference fit between adjacent rings to adjust the radial stress state at their interface，delamination during rotation can be mitigated，thereby improving grinding-wheel performance.
