为了改进槽型托辊组的支撑刚度,推导了物料横截面面积的计算公式,计算出了槽型托辊组的静态载荷,并在此基础上对其进行有限元分析,获得了托辊结构的应力分布及变形状态。以侧辊轴线倾角?为设计参数,采用FFE算法对槽型托辊组的支撑刚度进行优化设计,优化结果使?增大到22.3°,同时槽型托辊组的最大变形量减小了20.46%,使其支撑刚度得到了有效提高,为带式输送机托辊的结构设计提供了重要参考和依据。
In order to improve the support stiffness of the grooved roller set, the formula of the cross-sectional area of the material was derived and the static load of the grooved roller set was calculated. Based on this, the finite element analysis was carried out to obtain the roller structure The stress distribution and deformation state. Taking the axial inclination of the side roller as the design parameter, the FFE algorithm was used to optimize the support stiffness of the grooved roller group. The optimization result increased to 22.3 ° and the maximum deformation of the grooved roller group decreased by 20.46 %, So that the support stiffness has been effectively improved for the belt conveyor idler structural design provides an important reference and basis.
