Abstract

Intelligent Simulation Computing methods play an important role in solving computational mechanics problem, accurately as well as in engineering problems. Intelligence Finite element method is one of those numerical methods which uses differential equation to solve most of the problems. In order to optimize the low-vibration vertical mill, it is necessary to carry on the mechanical calculation and the intelligent numerical simulation analysis to the key components. In this paper, the working principle and structure of low-vibration vertical roller mills and forces of key component were analyzed intelligently. The size of main forces was calculated. A 3D simulation model of the rocker arm-roller system was set up and an intelligence finite element analysis was conducted based on the Ansys Workbench. The intelligent computing results showed that in the rocker arm-roller system, the maximum stress of lower rocker arm was located at the joint between shaft hole of lower rocker arm and groove corner. The maximum equivalent stress was about 150.87MPa. The maximum stress of upper rocker arm was located at the shaft hole joint in the middle of lower rocker arm and upper rocker arm. The maximum equivalent stress was about 106MPa. The maximum stress of roller was located at the contact area with the disc. The maximum equivalent stress was about 24MPa. Based on the intelligent numeral calculations, the maximum stresses of three key components were much lower than the yield strength of materials and the rocker arm-roller system of the proposed low-vibration vertical mill is reasonable.
