Abstract:
In order to reflect the actual dynamic balancing status of high-speed mechanisms,the equivalent kinematic model of mechanical system is established.The relationship between equivalent moment of inertia and the input speed fluctuation is investigated.The amplification of input speed fluctuation to exacerbate the dynamic balancing status is analysed.The possibility of reducing the input speed fluctuation by magnifying equivalent moment of inertia or decreasing its fluctuation is analyzed by taking a typical slider-crank mechanism with its balancing mechanism as an instance.The result shows that:it is more applicable to minish the input speed fluctuation and to optimize the dynamic balancing by adding moving components which can be used to increase the equivalent moment of inertia.The results provide a theoretical basis for researching the actual dynamic balance status and further improving the balancing design of high-speed mechanism.
