Particle damping has emerged as an effective passive method to suppress unwanted vibrations in a range of engineering applications. By utilising the inelastic collisions and friction between granular ...

Materials researchers have created a new composite material that combines two incompatible properties: stiff yet with a high damping capacity. A compressor hums, an air conditioning system rattles, a ...

Piezoelectric shunt damping is an innovative method for mitigating unwanted vibrations in structures by exploiting the electromechanical properties of piezoelectric transducers. When bonded to a ...

Hydrin-brand ECO has a long history of use in automotive applications due its exceptional heat and oil resistance up to 150°C, while maintaining flexibility at low temperatures down to -50°C. While ...

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...

A collaboration between the University at Buffalo School of Engineering and Applied Sciences and the U.S. Air Force Research Lab (AFRL) has shown it’s possible to electronically tune the frequency ...

Spring technology for damping is relatively old. Stagecoaches had leaf springs, early trains had large, crude, coil-spring buffers (to absorb shocks when cars bumped together) and early automobiles ...

In science and engineering, it's unusual for innovation to come in one fell swoop. It's more often a painstaking plod through which the extraordinary gradually becomes ordinary. Subscribe to our ...

Active or passive technology can be used to isolate vibrations from equipment. By employing active techniques, opposite but equal forces are created electronically via actuators and sensors to cancel ...

Increasing train speeds and greater axle loads on the rail lines of today has correspondingly increased the harmful impact of noise and vibrations on the areas around rail lines. The unevenness that ...
