Advanced science and Automation Corp. Releases DIS/Belt V1.3

Smithfield, VA- Advanced science and Automation Corp. (www.ascience.com) introduces DIS/Belt V1.3 - a specialized version of the DIS flexible multibody dynamics finite element code for modeling automotive and industrial belt-drives. The user constructs the belt-drive in a user-friendly graphical design environment using a library of objects that include belt, pulley, clutch, coupler, joints, and linear/rotational tension arms. DIS/Belt accurately and efficiently models the stick-slip behavior between the belt(s) and the pulleys. Other important physical effects such as belt bending, gravity, and asymmetric tension arm damping/friction are also accurately modeled. DIS/Belt predicts the dynamic response of belt-drives due to transient events such as 1-2 shifts, cycling of an accessory load such as the air-conditioner, or sudden loss in friction due to, for example, pouring water on the belt. DIS/Belt also predicts belt-drive stability/natural frequencies and response due to harmonic excitation from the engine.

For typical automotive belt-drives, DIS/Belt can perform 1 sec. of simulation in about 10 min. of computer time on a 3 GHz Pentium workstation. In addition, DIS/Belt offers parallel solution on shared-memory multi-processor workstations. DIS/Belt includes a powerful graphical post-processor for displaying an animation of the motion of the belt-drive and graphs of response quantities of interest.
