Abstract
The conveyor chain drive system which included four sprockets, four flat bars (chain guides) and one conveyor chain had been assembled into commercial software, MSC.ADAMS. The conveyor chain was connected with rollers for running on the chain guides. The multi-body dynamics (MBD) simulation was implemented to study the large displacement of chain components which happened during rotations of the symmetric model of the conveyor chain drive system. The physical experiment had obtained by construction of the conveyor chain drive system regarding the MBD model. The speeds of chain drive were adjusted by a gear motor with a converter. The trajectory of conveyor chain links which respectively meshed and ran on sprockets and chain guides was recorded by a high speed camera. Furthermore, impact-contact forces by a collision of components in the conveyor chain drive system during rotation were analysis. The comparison between MBD simulation and physical experiment of the conveyor chain drive system was performed for validation of simulation models. The MBD simulation results were in good agreement with the experimental data which obtained an average error of 3.95%.
Highlights
The conveyor chain has used in a long distance of producing lines to transport products or parts which have a heavy load
Multi-body dynamics system is a whole system composed of multiple bodies which are combined by the series of geometry constraints to calculate an expected motion
The computer aided design (CAD) model of the conveyor chain drive system was created by SolidWorks software which comprises of sprockets, conveyor chain and chain guides
Summary
The conveyor chain has used in a long distance of producing lines to transport products or parts which have a heavy load. This conveyor chain has many components which build up to move and hold products. The conveyor chain in producing line is an enormous system, complex to analyze with simulation method such as finite element analysis (FEA). The contact-impact constraint is a major condition to detect the precise of impact and to achieve the contact-impact force by MBD simulation [3]. The simulation of the conveyor chain drive system will be used to design and analyze the larger conveyor chain drive system of the rubber glove production line in the further works
