Vertical electromagnetic shaker is unable to test the heavy and large DUT, and the high position of center of gravity will cause side-slip, tumbling and overturning moment and this will always over-stress the suspension system of shaker and damage the system. Therefore, need for slip table for system for vibration testing is increasing to allow the testing to be done horizontally so that the system can withstand larger and heavier load.Functional structure of horizontal slip table can conduct testing for large and heavy DUT easily without malfunctioning. The limitation of normal vibration test can be overcome by changing the configuration of the shaker to horizontal position. Rigid integral structure and air damping system of shaker increase the reaction force of the system ,thus the influence of disturbance on the surrounding environment is minimized. The linear guide system ensures high strength if the slip table, and the cross vibration caused by asymmetry DUT is also minimized. The hydrostatic pressure system makes it possible to conduct vibration testing on large and heavy DUT which often produces large side-slip, tumbling and overturning moment due to high center of gravity. Oil film slip table is composed of a precisely ground natural granite and magnesium alloy equipped with linear guiding device of embedded or static hydrostatic bearing and provide users driving head of high frequency response and high strength.
Vertical expansion table
Expansion table is made of magnesium alloy to provide expansion for the armature. Reasonable and scientific design of the table can achieve a testing frequency of 2 Khz. Specific micro-structure provides reasonable vibration damping and minimize the amplification factor of high frequency resonance.
Customization of expansion table is provided. Such as round and square table.
Frequency range (Hz): 2~3000
