 Mechanical Engineering Analysis of conveyor belt system design is available, including determination of belt witdth, speed and throughput.   Analysis  provides motor torques and belt rating for any profile in the vertical or horizontal plane.   Analysis can involve design, auditing of a design for problems, proving a design concept or upgrade design of an existing system.

Conveyor Dynamic Analysis Expertise

In 1980, the first wave-based dynamic analysis of belts was developed.  Nowadays, dynamic simulation models and Discrete Elements are used to compute the rolling losses within the dynamic model.  A separate static analysis. is often not required for simple conveyor layouts.   

Starting and Stopping Analysis for Special Control Requirements

Belt Resonance - Eliminating Belt Flap Vibration

Ongoing Development in Software Algorithms for Simulation

Software Coding is in -house.
