The Research On Virtual Prototype Of Belt Conveyor With Twin Driving Respective Drums

The Virtual Prototype of belt conveyor with twin driving respective drums has been established by the virtual design method based on RecurDyn in this dissertation .It will accelerate the virtual technology to apply to the realm of belt conveyor's research and design, in order to reduce the product cost, shorten the product cycle and make the product suiting to the market better.Belt conveyor, is the most important equipment for bulk material transportation, which has some merits such as large capacity, long convey distance, continuous transportation, reliability and auto-control. Long-distance, large-capacity and high-speed belt conveyor, as the main torrent of modern belt conveyor, is used to improve product efficiency considerably, and some problem has emerged. The belt conveyor system is very complicated and the characteristic of its belt is peculiar, so we can't completely clean up the working characteristic. Nowadays the traditional static design method is used widely. The designers don't consider the dynamic characteristic sufficiently. Especially with regard to the high speed, long distance and large capacity belt conveyor, a lot of key technology does not solve perfectly in traditional design methods since dynamics characteristic is complicated. These problems, such as kinetics of heavy belt conveyor, force distribution among driving respective drums, distance between rollers, safety factor, restrict the design and production of heavy conveyor seriously.The Virtual Prototype technology is introduced in this dissertation. We choose the belt conveyor with twin driving respective drums as representative to study, using the new dynamic software - RecurDyn.This research is proceeding strictly according to the design route of Virtual Prototype. The procedure comprises simplification of belt conveyor with twin driving respective drums, 3D modeling, belt separating into micro segments. Then a simplified Virtual Prototype is completed. The Virtual Prototype is simulated under the working condition in the virtual environment of RecurDyn, and some tension sensors are arranged to measure the belt tension real time variation. The results have showed the correctness of simplified Virtual Prototype and the feasibility of Virtual Prototype of heavy conveyor. After improving the simplified Virtual Prototype, the Virtual Prototype of belt conveyor with twin driving respective drums has been accomplished. A good solution is provided to design and research works of belt conveyors.
