超高速陶瓷CBN砂轮结构优化设计
Optimization Design of Vitrified CBN Wheel Structure in Super High-speed Grinding
摘要
Abstract
An optimization objective was set up to control the radial displacement and to reduce the equivalent stress of the super high-speed grinding wheel.By established models for the connection between inner micro-unit's displacement and stress of wheel base,strength check of the theoretical formula about variable cross-section wheel was also established.A finite element analysis method was used to optimize wheel base type and material.The wheel pneumatic power and flow field temperature under ultra-high speed situation were also analyzed.Taking into account the characteristics of segment wheel,wheel segments number and thickness were optimized.The study has shown that the hyperbolic-type titanium alloy base wheel has a clear advantages to restrain the radial expansion and the average equivalent stress of wheel while its segments number and size have proper certain optimization value.关键词
