Abstract
The paper focus on studying the dynamic state of a ϕ 600 ́ 900mm laboratory ball milling added vibrating. Under the vibration movement, the calculation model should consider the factors which had been changed due a lot of loading condition. Here we present a new approach via finite element analysis to analysis the effect of the cylinder with alternative load. In this case, it can be gotten the load curve and the maximum and relatively stable load by calculation via the PFC3D software with a couple of data sets of parameters. Then, the shell's stress and strain can be obtained under the above two loads. According to the result of the FEA, the effect under the special load can be used to verify whether the cylinder of vibrating ball milling is safety and show that the cylinder's radial deformation is maximum and always concentrate on the middle zone of the cylinder and the manholes around.
