The slip table can be coordinated with an electro-dynamic vibration shaker to carry out three-direction vibration tests. Its small carrier (table) weight helps improve the overall load capacity. In other words, the test platform can support the load with a larger size and greater weight.
Based on connection methods, this product is categorized into integrated type and split type. In view of different guiding way, it can be divided into GT series and BT series. The GT series adopts V-shaped guiding way, and the BT series comes with hydrostatic guideway.
The vibration system equipped with a slip table can respectively accomplish the X, Y and Z-direction vibration tests for parts or entire machine. Also, it can be used together with the temperature and humidity test chamber to form an integrated environmental testing system.
The area and thickness of a sliding plate determines the quality of an active system. It may also affect the upper limit of frequency of the shake table. The indicators of table listed below pertain to all standard products of our company. The slip table can be customized according to the special requirements of users. It conforms to JB/T 6869-93 standard.
Characteristics
Convenient Operation
Distinct trunnion and guide bearing allow the horizontal and vertical switching to be realized easily. An electric power steering unit is ideal for use in a vibration shaker with above medium thrust, which makes switching more convenient.
Integrated Design
Integrated design allows the slip table and vibrator to share one base, which features high stiffness, easy installation and convenient commissioning. The integrated type has achieved national patent. It can be installed without a dedicated base.
The split design vibratory table is widely applied to the measurement of large-sized and complex-dynamics specimens. This design gives convenience for hoisting.
GT Series with V-shaped Guiding Way
The GT series slip table consists of the sliding plate, V-shaped rail, connectors, granite slab, base, and the built-in oil source. The built-in fuel supply pump is marked by compact structure and easy operation. The number of V-shaped guide rail varies with the size of our product. This kind of V-shaped guide rail is provided with an ultra high resistance to overturning moment.
Model Selection Guide
The shock test equipment may be affected by the overturning moment, inertia moment, center-of-gravity position, and the height of center-of-gravity of specimen. Therefore, its safety factory is recommended to be more than 1.2 times as high as theoretical force.
BT Series with Hydrostatic Bearing
The BT series slip table is made up of the sliding plate, hydrostatic bearing, connectors, granite slab, base, and the stand-alone hydrostatic oil source. The hydrostatic bearing can provide a higher resistance to overturning moment. It is suitable for testing heavy-load specimens. The higher the number of hydrostatic bearings is, the greater the resistance to overturning moment will be.
LTT Series with Medium-Pressure Guidance Bearing
The medium-pressure slip table is designed with slip plate, medium-pressure guidance bearing, coupling, natural granite block, base and oil return basin & "oil guard" protection system. Medium-pressure bearings feature high anti-overturning moment, making it suitable for testing objects with high loads. The more hydrostatic bearings are installed, the higher the anti-overturning moment is.
