SYSTEM DATA. Slip Tables and Combos for Vibration Test Systems

1 SYSTEM DATA Slip Tables and Combos for Vibration Test Systems The LDS range of oil film slip tables are designed for ease of installation while providing the maximum flexibility to the test engineer. For 3-dimensional testing applications, we recommend a LDS trunnion mounted electrodynamic shaker and slip table. Combined in one fabricated frame, this system provides easy installation and mobility. For testing very large or complex payloads, we recommend a stand-alone trunnion mounted shaker a separate slip table on a seismic base. This configuration provides the ultimate pitch, roll and yaw restraint for the vibration table. Two types of slip tables are available: Hydrostatic Bearing Tables (HBT) or Low-pressure Tables (LPT). The HBT series provides the ideal solution for strenous vibration test requirements, and the use of linear hydrostatic bearings allows for heavier load carrying capabilities. The LPT series provides a cost-effective solution for use of vibration tables in most production line and research applications. These slip tables use guidance bearings to minimise axial distortion and an oil film for load support. All LDS slip tables use custom designed, rugged steel chassis allowing for maximum stiffness for the greatest payload. Combo Systems The largest of the LDS V700 series and all V800 and V900 series electrodynamic shakers can be supplied as a combo system. All feature the LDS Lin-E-Air body isolation and guidance system, which ensures the body of the electrodynamic shaker is maintained on the central line, minimising distortion and maximising low frequency and payload capabilities. General Features: Available as stand-alone table or combined a shaker as a complete combo system Standard sizes range from cm (24 59 in); custom sizes are available upon request Tool grade magnesium slip plates Space-efficient design minimises floor real estate Patented shear pin and tension bolt driver bars Cast composite granite base provides for high stability and no natural defects Oil film for load support minimises plate rippling Body and base isolation suspension for body of shaker Air glide and castor mobility available HBT Series Features: Available in two displacement sizes: 75 mm (3 in) and 50.8 mm (2 in) Additional hydrostatic load carrying bearings Bearings can be configured to accommodate different load types Linear bearings provide axial restraint for low distortion while additional bearings provide tolerance for thermal expansion and contraction LPT Series Features: Available in two displacement sizes: 75 mm (3 in) and 50.8 mm (2 in) Linear bearings to minimise distortion Bearings positioned on centre line, eliminating the need for adjustment as a result of plate expansion and contraction caused by thermal changes Applications: 3-axis testing Avionics and military hardware testing Space flight simulation Automotive component testing Electronic assembly testing LPT series: General payloads HBT series: Exceptional payloads Typical LDS V800 shaker LPT900 slip table
