Carry and put 1 outer surface.The quantity of adhesion type tamping equipment 2 is 2.There is provided vibration frequency be 0 to
200Hz, non-loaded amplitude (containing bogey 1) is 0 to 2.0mm, until material is all unsnatched.
Bogey 1 is fixed on above described measurement apparatus；
As in figure 2 it is shown, bogey 1 includes bearing part and the bottom of reversed round bench shaped, bearing part
It is gemel connection with bottom, and plug-in switch is passed through in the bottom side relative with bearing part gemel connection
4 are fixed on bottom surface, bearing part.A diameter of 10cm-70cm of bogey 1 upper bottom surface, bottom surface
A diameter of 10cm-60cm, and the diameter of bogey 1 upper bottom surface is more than bottom surface diameter, bottom with under
Bottom shape is identical, and bottom area is slightly larger than bottom surface area.
Measurement apparatus includes measuring box 6 and dip stick 7, and dip stick 7 is arranged on measuring box 6 in crosswise
Upper surface.The geometric center lines of bogey 1 is vertically through the right-angled intersection point of dip stick.
Bogey 1 is fixed on above described measuring box 6 by support 5.The quantity of support 5 is 4,
It is evenly distributed on bogey 1 lateral wall, and the tie point of four supports 5 and bogey 1 is to surveying
The vertical range of amount box 6 is the most equal.
Straight vibrating spear 3 is positioned at the geometric center point of bogey 1 as the center of circle, and radius is the circle of 5cm
In.
Current supply circuit 8 includes three row parallel circuits, wherein two is classified as three-phase alternating current, and one is classified as blow-up
