MB Dynamics Voice Coil Vibrator Shaker Model # C-40 * up to 18 KVA input power * full function to 3000 Hz * no resonance under 2000 Hz * Manufactured By: MB Dynamics * ~4022 lbs, 44 by 42 by 34 inches raw Looks to be in good order. No amplifier included! We have not tested it as we don't have anything to power it with. MB Dynamics describes this product as: The C-Series HP Shakers offer exceptionally high acceleration levels with stiff armatures, have 50mm of stroke (continuous duty), full performance SINE & RANDOM tests out to 3000 Hz (usable, at reduced levels, out to 4000 Hz), rugged armatures with no resonances below 2000 Hz, reliable for shock testing using classical pulses (half sine, sawtooth, etc.) as well as time history replication, force ratings from 5kN to 80kN, vertical & horizontal operation, direct-coupled, automatic payload recentering, and trunnion isolation. For more information please visit: MB Dynamics C-Series Shakers The Model C-40 is capable of 5,000 SINE lbs pk, 4,000 RANDOM lbs rms, 8,000 SHOCK lbs pk, 110 Max Accel g's pk, 70 SINE Velocity ips pk, 90 SHOCK Velocity ips pk, 220 30g 11ms Payload, 2 Cont. Duty Stroke in pk-pk, 2-3 k Full Preform Freq Range Hz, (Armature) 2,550 Axial Res. Hz, 42 Wt lbs, 12 Outer Bolt Circle Inches, 13.25 Diam Inches. With the P-Series Amplifiers (NOT INCLUDED) the shaker is capable of 18 kVa Rating, DC Coupling DC/Match, Configuration= Max Force & Max Velocity This unit is used for vibration testing: Vibration testing is accomplished by introducing a forcing function into a structure, usually with some type of shaker. Alternately, a DUT (device under test) is attached to the "table" of a shaker. For relatively low frequency forcing, servohydraulic (electrohydraulic) shakers are used. For higher frequencies, electrodynamic shakers are used. Generally, one or more "input" or "control" points on the DUT are kept at a specified vibration level. Other "response" points experience maximum vibration level (resonance) or minimum vibration level (anti-resonance). Two typical types of vibration tests performed are random- and sine test. Sine (one-frequency-at-a-time) tests are performed to survey the structural response of the device under test (DUT). A random (all frequencies at once) test is generally considered to more closely replicate a real world environment, such as road inputs to a moving automobile. Most vibration testing is conducted in a single DUT axis at a time, even though most real-world vibration occurs in various axes simultaneously. MIL-STD-810G, released in late 2008, Test Method 527, calls for multiple exciter testing.
