在软件Pro/Mechanica、ANSYS平台上建立了筛箱的有限元模型,并对其进行动态特性分析,获得了筛箱低阶固有频率与模态振型,找出了筛箱在额定载荷作用下各部位的动态应力分布规律。为该筛的改进设计及后续筛箱动态强度的试验研究提供了必要的依据。
The finite element model of sieve box was established on software Pro / Mechanica and ANSYS platform, and its dynamic characteristics were analyzed. The lower natural frequency and modal shape of sieve box were obtained, and the effect of rated load on sieve box Various parts of the dynamic stress distribution. It provides the necessary basis for the improved design of the screen and the experimental study on the dynamic strength of the subsequent screen box.
