图1介绍了双向撞击式水平微震装置。钩状的双轴激振器1作水平方向振动,钩子的两个内平面上固定有橡胶撞击板2,在撞击板之间自由地搁上把手的横杆3后有间隙κ,横杆和安放在橡胶减振垫上的工艺装备4固接。间隙κ的选择应使当系统进入微震时,轮流在左右方向具有必要的撞击强度。且激振器卸荷,这就允许大大减少所消耗的功率和不平衡静质量矩的数
Figure 1 shows a bi-directional impact microseismic device. The hook-shaped biaxial vibration exciter 1 vibrates in a horizontal direction, rubber hitting plates 2 are fixed on the two inner planes of the hooks, and a gap κ is provided after the hitch crossbar 3 is freely placed between the impact plates. The cross bars and Placed in the rubber cushion on the process equipment 4 fixed connection. The choice of clearance κ should be such that when the system enters microseism, it has the necessary impact strength in the left and right directions. And exciter unloading, which allows to greatly reduce the consumption of power and unbalance static mass moment
