PRODUCT DATA LDS V8900 Shaker High-Force Electrodynamic Shaker The LDS® V8900 shaker is ideal for vibration and mechanical testing using sinusoidal, random or transient excitation. Systems are available in various forms to meet customers’ requirements, for example: Lin‐E‐Air trunnion‐mounted with a body rotation gearbox; combined with a horizontal hydrostatic slip table; silencer for shaker cooling fan; thermal management; quiet mode. V8900 Combo-Mounted Shaker with HBT Slip Table Trunnion-Mounted Shaker Specification (for combo performance contact your local Bruel & Kjaer representative) Performance Parameters Armature Diameter Sine Force (peak)* Lin-E-Air Body Resonance Overturning Moment Restraint Suspension Axial Stiffness Max. Acceleration (sine peak)* Suspension Cross-Axial Stiffness Suspension Rotational Stiffness Shaker Body Mass Total Weight Max. ½-Sine Peak Shock Force† with XPA88K Amplifier Effective Mass of Moving Element: 17 raised (hexagonal) inserts Velocity (sine peak)* 29 raised (hexagonal) inserts Full field Reduced field Usable Frequency Range ▪ Internal Load Support Capacity Recommended Amplifier * The force, velocity, and acceleration parameters detailed here are based on the shaker when driven by the recommended LDS XPA-K amplifier. † Random and shock ratings assume an m40 payload as specified by ISO5344; shock pulse 2 ms. ▪ Force will be reduced above 2200 Hz dependant upon payload and payload fixture dynamic response.
