本文提出回转惯性力效应,并导出回转惯性力公式。回转惯性力效应不仅转体的理论分析要考虑它,而且凡是转体机械的设计,跟转体动有关的安装、操作都应考虑它,特别高速转体更应注意,它将导致转动构件的疲劳、破坏。 This paper proposes the effect of inertial inertial force and derives the formulae for the inertial inertial force. Rotary inertial force effect not only considers the theoretical analysis of the swivel body, but also the design of the swivel machine. It should be considered when installing and operating the swivel body. Special attention should be paid to the high speed swivel. It will lead to the rotation of the component. Fatigue and destruction.
