摘要

研究了重型胶圈给料机在冲击载荷作用下,承载板与支承导轨之间的间隙接触问题。基于能量法计算落矿冲击力,利用ANSYS Workbench对带间隙的结构进行非线性接触有限元分析。结果表明:在接触的第一个时刻,初始接触形状为近似线性接触,随后在接触线附近发生变形,并迅速由线性接触演变为表面接触;接触应力分布沿初始接触边界向外扩散并逐渐减小,在接触边界处发生应力集中。距离不同时,接触面积形状相似,但距离大时,接触面积小,应力分布更集中。裙边给料机的非线性接触计算揭示了板轨在冲击力作用下的瞬时接触过程,确定了距离大小对接触性能的影响,为距离值的选择提供了理论依据。

Contact analysis of heavy-duty apron feeder with clearance
The problem of clearance contact between the bearing plate and the supporting guide rail is studied when the heavy‐duty Apron Feeder is subjected to impact load. Based on the energy method, the impact force of the falling ore was calculated, and the nonlinear contact finite element analysis of the structure with clearance was performed using ANSYS Workbench. The results show that at the first moment of contact, the initial contact shape is an approximately linear contact, and then a deformation occurs near the contact line, which quickly evolves from a linear contact to a surface contact. The contact stress distribution is diffused outward along the initial contact boundary and gradually decreases, and the stress concentration occurs at the contact boundary. When the distance is different, the shape of the contact area is similar, but when the distance is large, the contact area is small and the stress distribution is more concentrated. The nonlinear contact calculation of the skirt feeder reveals the instantaneous contact process of the plate rail under the impact force and determines the influence of the distance size on the contact properties, which provides a theoretical basis for the selection of the distance value.

期刊介绍: Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
