DMA Testing Services for Characterization
a fixed rate. The DMA uses samples that can be in bulk solid, film, fiber, gel, or viscous liquid form. Interchangeable fixtures are employed to allow you to measure many properties, including: modulus, damping, creep, stress relaxation, glass transitions, and softening points. Dynamic Mechanical Analysis measures viscoelastic properties of materials: · Elastic modulus (storage modulus, E'). · Viscous modulus (loss modulus, E''). · Damping coefficient (Tan delta...

Sherborne Sensors
A640 Series Precision Solid State Accelerometers
from ±1g to ±20g with ±5Vdc output, the Sherborne Sensors A640 series features an advanced solid-state MEMS sensor, incorporating integral air damping. Unlike fluid-damped devices, air damping is essentially independent of temperature, which enables the accelerometer to reliably perform over a very wide temperature range (-40 ° to +100 °C), with essentially zero temperature coefficient of damping ratio. Units are compensated for effects of temperature on both sensitivity... (read more)

Shifting Critical Speed Out of the Operating Range by Changing From Tilting Pad to Sleeve Bearings (.pdf)
One property of heavily to moderately loaded sleeve bearings is the resulting asymmetric stiffness and damping coefficients. These asymmetric properties often result in split first critical speeds. Since the horizontal stiffness is much softer than the vertical, a horizontal first critical speed
