砂轮片旋转状态下应力分布研究

Research on Grinding Wheel Piece Stress Distribution under Revolving Condition

通过理论分析求得砂轮片在空转状态下的应力分布公式,利用有限元仿真软件分析了砂轮片在空转状态下的应力分布,经过两者分析比较,证明结果是一致的,即砂轮片切向应力总是大于径向应力,等效应力基本上等于切向应力,应力最大处在内孔位置,并且随着转速的提高,砂轮片的破坏趋势愈发明显.分析结果为砂轮片失效机理的研究提供了依据.

This paper has obtained the stress distribution formula through theoretical analysis, and analyzed the stress distribution using finite element simulation software when the wheel piece was under the idle operation condition. After comparison, the proof result is consistent, namely： the grinding wheel piece tangential stress is always greater than the radial stress, the equivalent stress is essentially equal to the tangential stress, the maximum value of stress is in inside diameter position, and the tendency of destruction becomes more obvious with the improvement of the speed. Thus it has built the good foundation for the failure mechanism＇s research of the grinding wheel piece.
