To help process design silo containing wheat, rice more effectively meet the urgent demand of the system stockpiles, this paper built a program calculations, tests strength, aims to optimize the design of silo. This program combines powerful computing capabilities of ANSYS in finite element method and the ability to design intuitive interface of Visual Basic. The authors proposed a process for calculating the silo as round and square form of the Long An Machinery Industry Joint - Stock Company (LAMICO) and realize the software calculates silo CCMSilo.
