Slip Tables, Head Expanders and Thermal Barriers

Our range of Vibration test systems feature LDS slip tables, head expanders, and thermal barriers, provide enhanced testing capabilities for our range of medium- and high-force shakers. Our low-pressure tables and hydrostatic-bearing tables can be supplied as a combo system – or as separate slip tables for mounting on your existing vibration system.

SLIP TABLES:

A slip table typically consists of a magnesium plate sitting atop a smooth granite block, with a lubricating film in between. For testing applications requiring three individual axes, we recommend an LDS trunnion-mounted shaker and a slip table. Both are housed in a frame that connects to the shaker’s armature, enabling it to excite payloads in the horizontal position.

Applications:
  • Three-axis testing, including test of complete satellite systems
  • Testing of avionics and defence hardware
  • Space flight simulation
  • Testing of commercial and military aircraft assemblies
  • Automotive component testing
  • Testing of electronic assemblies
  • Packaging and transport testing
LOW-PRESSURE (LPT) SERIES SLIP TABLES

LDS® Low-pressure (LPT) series slip tables are designed for horizontal- and three-axis testing of payloads up to 1500 kg (3307 lb), such as automotive assemblies. LPT slip tables are suitable for general-purpose vibration testing systems which offer a cost-effective solution for most R&D and product verification applications, including testing of military equipment, electronic assemblies, and aircraft and automotive components.

HYDROSTATIC BEARING (HBT) SERIES SLIP TABLES

LDS® Hydrostatic Bearing (HBT) series slip tables provide the ideal solution for strenuous vibration test requirements in R&D and product qualification for a variety of industries, including automotive, aviation, aerospace and defence, and packaging and transport. These tables offer increased stiffness, dynamic stability and damping, so that loads with high or off-set centres of gravity and high overturning moments can be tested safely and efficiently.

HEAD EXPANDERS

Head expanders consist of a large platform that is bolted to the shaker’s load table. They are used to increase the effective mounting surface to accommodate larger or numerous payloads, a head expander increases the capability of existing shaker systems. LDS® Head Expanders are cast from a high-strength, aerospace-grade magnesium alloy with excellent damping properties to minimize force dispersion. They have a usable frequency range from DC – 2000 Hz. To prevent corrosion, non-machined parts are painted, and machine parts are coated with lubricant.
