研削砥石の三次元応力解析

Recently, high-speed production grinding has been used as one of economical methods of productions. In this working, as the circumferential velocity of grinding wheel will reach 5400 m/min, it is required to investigate the bursting strength of highspeed rotating wheels.
In this paper, the effects of the clamping force transmitted from flange and the centrifugal force will be analyzed by applying the three-dimensional elastic theory on the finite hollow cylinders. On the other hand, the effects of the grinding force will be discussed by using the finite element method to analyse the axi-symmetrical elastic body under un-symmetrical load systems.
From the theoretical and the numerical analyses, it becomes obvious that the most im-portant stress is the circumferential stress σ_θ caused by the centrifugal force, and the clamping and the grinding forces disturb this stress.
