Harvard engineers have demonstrated a new 3D printing technique that allows the arrangement of short fibers in the printed material to be finely tuned. The spinning printer head gives the technique ...

Metamaterials with stiffness tunability have demonstrated great potential in mechanical systems that operate in variable environments. Real-time ...

Many products have pin connections to let parts open, close, turn, and swing. Simulating these assemblies using traditional finite-element techniques, however, takes a great deal of time and ...

The first article in this series examined a pseudo-ideal gear reducer to demonstrate that free play between adjacent parts becomes lost motion Precision gear reducers typically exhibit less than 10 ...

A team of researchers has demonstrated a novel 3-D printing method that yields unprecedented control of the arrangement of short fibers embedded in polymer matrices. They used this additive ...

High performance servomechanisms capable of dynamic precision movement improve industrial productivity by increasing machine cycle times and throughputs. Precision planetary servo gearheads, often an ...
