Beam-Like Belt Modeling for Vibration Analysis in Belt Mechanisms and Conveyor
Systems
Masters thesis,
Report 2003.TL.6793, Transport Engineering and Logistics.
For conceptual and other stages of designing of a multibody system, the
analysis of vibration, to determine the natural frequencies of all modes of
vibration of the system, is essential. For this purpose, several researchers
have devised a number of methods.
This thesis has adopted the Finite Element Method, suggested by scientists
like Schwab, which is based on the idea of superimposing small linear
deformations (vibrations) while the multibody system is on a general non-linear
rigid body motion.
In this thesis, a new beam-like belt element has been modeled and vibration
was analyzed according to the aforementioned method. The belt element and its
kinematic, dynamic and vibration analysis was implemented in existing software
called RUNMEC and have been tested for several belt mechanisms and conveyor
systems.
At the end, conclusions and recommendations have been drawn based on the
results of the tests as compared with experimental and theoretical resuits.
