改进共振筛的基本方向之一,是设计三质体系统的共振筛,因它在十分稳定的工作制度下能保证工作机构有较大的振幅。在共振筛上装设非线性弹簧杆,会使它的优点大大减少,因为大部分传动功率将消耗在非线性弹簧的滞后上。本文将研究具有线性弹簧杆的共振筛的工作制度和寻求调整工作制度的途径,在这种状态下消耗的功率最少,并获得稳定的工作。筛子质体运动微分方程式的建立。为了建立筛子质体运动微分方程式,座标的起点取偏心轴的迥转中心(这时偏心轴在瞬时t=o时处于平衡位置), (见图1)。轴
One of the basic directions to improve the resonance sieve is to design the resonance sieve of the three-plastid system because it can ensure a large amplitude of the working mechanism under a very stable working system. The installation of a non-linear spring bar on a resonant screen greatly reduces its benefits because most of the drive power will be dissipated over the non-linear spring hysteresis. In this paper, we will study the working system of a resonant screen with a linear spring bar and the way to find a working system that consumes the least amount of power and achieves stable work. The establishment of differential equation of sieve plastid motion. In order to establish the differential equation of plastid movement, the starting point of the coordinate is taken as the center of eccentric rotation (at this time, the eccentric shaft is in equilibrium at instant t = o) (see Figure 1). axis
