When Gregor Blanco of the San Francisco Giants hit a line drive over center field smacking Tigers' pitcher Doug Fister right in the head last night in Game Two of the World Series, he almost certainly ...

Centrifugal pendulum vibration absorbers (CPVAs) represent a pivotal solution for mitigating torsional vibrations in rotating systems, particularly in automotive and industrial applications. These ...

HAMPTON, Va. — NASA’s Constellation program office has asked engineers at Langley Research Center here to develop hardware intended to protect astronauts from potentially dangerous levels of ...

We have learned that an effective way to passively control vibration is through the usage of a “vibration absorber”. A typical vibration absorber is a single-DOF spring/mass/dashpot system that is ...

have been wrestling with for the past six months. Engineers at NASA’s Marshall Space Flight Center in Huntsville, Ala., became concerned last October after simulations suggested that vibrations ...

This is a preview. Log in through your library . Abstract The objective of this study is to develop the first fully passive nonlinear piezoelectric tuned vibration absorber (NPTVA). The NPTVA is ...

NASAengineers have come up with a dual shock absorber solution to the problem ofexcessive vibrations with the new Ares I rocket that will launch the agency?sOrion space shuttle replacement.

Knock noise induced by automotive shock absorbers has serious influence on driving comfort and vehicle quality. Some research focusing on knock noise had been introduced in the past. However there is ...
