The belt conveyor is one of the modern major bulk material handling equipment . The drum belt conveyor drive components , its role has two : First, power transmission , and change the direction of the conveyor belt running . Belt conveyor the drum design quality , related to performance , security and reliability of the entire conveyor system . At present, the domestic design of the drum is commonly used approximate formula has been able to meet the engineering needs for small and medium-sized drum , large drum of this design approach , the actual results and Engineering gap , difficult to guarantee its security and reliability . Due to the lack of precise calculation method , if the blind to increase the safety factor causes the structure size becomes large , the weight increase , the intensity is not significantly improved while increasing the cost . This paper includes the following aspects : First, the structure of belt conveyor design calculation methods were analyzed , corrected for formula , perfect and unified design calculation content . Secondly , the use of ANSYS software using the bottom-up modeling approach , in accordance with the key points , lines, surfaces , and the order of the entities to establish a driving drum model ; drum solid elements , in order to improve the computing speed and accuracy , mapped meshing ; analysis and determining the drum load , discrete processing load on the cylinder surface , to be applied to the drum the nodes of the finite element model , using the direct method for solving ; results post-processing to analyze the stress and strain on the drum member . Development platform, third, ANSYS APDL language to build the drum of the kernel of the general-purpose computing program , the use of general-purpose computing program UIDL language development belt conveyor interface ; the AutoCAD support platform , VC environment , development a driving drum parametric drawing system . This article has some practical value and significance , belt conveyor belt conveyor design calculation methods and written a general-purpose computing procedures and parametric drawing system can greatly improve the the drum design quality , shorten the design cycle .
