IVRESS/Belt
IVRESS/Belt is a time-accurate finite element / multibody dynamics tool for predicting the dynamic response of belt-drives. IVRESS/Belt allows belt-drive designers to quickly build, analyze, and visualize belt-drives in an intuitive object-oriented graphical design environment. Typical applications include automotive accessory belt-drives, pumps, compressors, washing machines, and dryers.
