Turnstile Shock Absorber Applications
over a long period of time delivering energy absorption to the turnstile mechanism. (view article on line here: http://www.enidine.com/News/Product-Spotlight/Turnstile-Applications/ ). During development of a wheelchair accessible variation of a turnstile it was discovered that the shock absorber did not provide enough resistance to the increased mass and forces being applied during its operation. The gear train is common with the standard turnstile, so redesigning the unit for a larger type... (read more)

Spend Your Time Engineering, Not on Differential Equations
with something as simple as a spring-mass-damper system, for example, users must draw the free body diagram and then generate the governing equations between the physical components. Next, users must derive the differential equations for the system, convert them to integral form, and, finally, break
Whole lot of shakin' goin' on
, there is relative motion when the frequency of a noise source coincides with a mechanical resonance. The amount of relative motion depends on the input noise level and the mechanical gain or amplification at resonance. The mechanical structure can be modeled as a second-order, mass-damper-spring
