摘要
基于轮式移动装船机的设计方案及参数,对装船机进行总体设计;根据轮式移动装船机的臂架结构特点,提取其特征参数,然后运用Ansys的APDL语言建立臂架的参数化模型,并对臂架结构进行有限元分析;最后运用Ansys软件和优化设计技术对臂架结构进行优化分析,在满足设计要求的情况下,实现臂架的经济性和可靠性。得出结果如下:由于臂架下铰接距进料口较近,其受力也较大,臂架头部相当于悬臂梁且悬挂着溜筒,臂架最大应力出现在下铰接处,最大变形量出现在臂架头部;臂架结构采用变截面设计可以大大降低结构总重。
Based on the design scheme and parameters of the wheeled mobile ship loader,the overall design of the ship loader was carried out.According to the structural characteristics of the boom of the wheeled mobile ship loader,the characteristic parameters were extracted,then the parametric model of the boom was established by using the APDL language of ANSYS,and the finite element analysis of the boom structure was carried out.Finally,the boom structure was optimized by using ANSYS software and optimization design technology.Under the condition of meeting the design requirements,the economy and reliability of the boom are realized.The results are as follows:because the lower articulation of the boom is close to the inlet and outlet,its force is also large,the head of the boom is equivalent to the cantilever beam and hangs the chute,the maximum stress of the boom appears at the lower articulation,and the maximum deformation occurs at the head of the boom;the total weight of the structure can be greatly reduced by adopting variable cross-section design of the boom structure.
