在振动机械的设计计算里,特别是在某些弹性元件刚度较大因而重量也较大的振动机械,如电磁振动给料机等的设计计算里,弹性元件本身的质量不容忽视。弹性元件在参与振动的过程中,它本身各部分的振幅和速度与振动槽或平衡重的振幅和速度并不相同,这是十分明显的。例如图1所示为一种单质点振动输送机的情况,板簧上端与槽体铰接,下端与底座固
In the design and calculation of vibrating machinery, especially in the design and calculation of certain vibrating machinery such as electromagnetic vibrating feeder and so on, which have greater rigidity and heavier weight of the elastic element, the quality of the elastic element itself can not be neglected. It is quite obvious that the amplitude and speed of the elastic element in the course of its participation in vibration are not the same as the amplitude and speed of the vibration channel or counterweight. For example, Figure 1 shows a single particle vibration conveyor case, the upper end of the leaf spring hinged with the tank, the lower end and the base solid
