在分析与设计惯性式振动输送机时,必须建立它的运动微分方程,其中包括系统质量与转动惯量的计算、阻尼的确定、弹性系统的计算以及激振器的计算等,然后求出方程的解。由于单质量双轴平行惯性式铅垂振动输送机运动微分方程的精确形式,往往会出现时间的周期性系数,不便于实际应用。因此,必须进行合理的简化,把它变成简单、易用的形式。本文对这种输送机的运动进行一般性的推导,建立精确的运动微分方程。所得到的方程不仅适用于正常工作的情况,而且适用于输送机的启动和制动过程。进而,把这精确方程变为简化方程,并指出这一简化的可靠性。
In the analysis and design of inertial vibration conveyor, it must establish its differential equations of motion, including the calculation of the system mass and moment of inertia, the determination of damping, the calculation of the elastic system and the exciter calculation, and then find the equation solution. Due to the precise form of the differential equation of motion of a single-mass parallel bogie vertical vibration conveyor, the periodic coefficient of time tends to appear, which is inconvenient for practical application. Therefore, a reasonable simplification has to be made to turn it into a simple, easy-to-use form. This article generalizes the movement of the conveyor and builds accurate differential equations of motion. The resulting equation is not only suitable for normal working conditions, but also for the conveyor start-up and braking process. In turn, this exact equation is reduced to a simplified one and the simplified reliability is pointed out.
