摘要
对叉车的可拆卸式前叉(安全前叉)装置进行力学性能有限元分析,结果表明:该前叉装置在临界工况下,应力、形变最大的位置均出现在前叉座与叉架接触的下部,最大应力可达25 MPa,低于车架材料的屈服强度;最大位移出现在前叉尖端,为1.111 mm,满足设计要求。
The mechanical finite element analysis of the front safety fork device shows that,under the critical working condition,the position of the maximum stress and deformation of the front fork device appears in the lower part of the contact between the front fork seat and fork frame,and the maximum stress can reach 25 MPa,lower than the yield strength of the frame material;the maximum displacement occurs at the front fork’s cusp,which is 1.111 mm and meets design requirements.
