Horizontal Slip Table
A Shaker, in horizontal orientation, does not offer any area to mount objects as the Armature’s head is perpendicular to Earth. Therefore, in order to achieve vibrations in the X and Y axis, a Horizontal Slip Table (HST) is used which offers a bed parallel to Earth. This bed connects to the Armature with a coupling when the shaker is in horizontal orientation. The HST bed and its coupling to the Armature are manufactured by welding magnesium alloy tool plates. Coupling is designed to operate in tension and compression mode to yield highest transmissibility. Low or high pressure hydrostatic bearings are placed at different locations based on the design of HST to constrain its motion in the same axis as the Shaker. A granite block is placed beneath the HST bed and a consistent oil film is generated on this block and in the bearing to remove friction and provide dynamic support. As the motion of this bed is constrained to one direction, the object is rotated by 90° on the table to switch between X and Y axis. A system integrated with HST is capable of testing objects in all three axes, one at a time.
Major Sub Systems of the Horizontal Slip Table are:
Trunnion Assembly
An optimised gear based pivoting system to turn the shaker from its vertical position to a horizontal position using mechanical or electrical means. Locking bolts are provided on either sides to lock the trunnion assembly at the point where the shaker is precisely aligned vertically and horizontally. A mercury switch is used to detect the orientation of the shaker by the Power Amplifier to enable or disable relevant interlocks automatically.
Shaker to HST Coupling
Our bull nose design based adaptors for attaching the shaker’s armature to the HST’s bed are manufactured by welding high quality magnesium alloy tool-plates. Interface with the armature uses every insert of the armature and interface with the bed uses bolts placed at a slight angle from the axis of vibration to provide maximum transmissibility and ease in operation. The final outcome is that the centre of the armature, centre of the adaptor and the centre of the bed fall in the same axis.
Combo Base
As most of the testing is done in all three axis, changing orientation from vertical to horizontal and vice versa happens very frequently. Therefore, both Shaker and HST are bolted on a single platform with very tight tolerances to ensure proper alignment every time you turn the shaker.
