摘要
针对掘进机液压缸的质量占比相对较大、能量利用率低等不足,提出了一种基于ABAQUS的液压缸轻量化设计方案。通过分析掘进机液压缸工作原理,以活塞杆作为液压缸轻量化设计目标,采用结构优化的思路将活塞杆改为空心结构,并运用Creo三维建模软件构建了空心活塞杆几何模型,利用ABAQUS中的Tosca优化模块进行拓扑优化,得出最佳模型参数。有限元分析结果表明:空心活塞杆的整体变形量较小,最大变形发生在端口位置,值为0.138 mm;最大应力发生在活塞杆与活塞的连接部位,最大值为342.18 MPa,在许用应力范围内,满足轻量化设计要求;轻量化设计后的活塞杆质量降低约22.85%,效果明显。
A lightweight design scheme of hydraulic cylinder based on ABAQUS is presented to overcome the shortcomings of relatively large proportion of the quality of the hydraulic cylinder and low energy utilization. By analyzing the working principle of the hydraulic cylinder of the roadheader,taking the piston rod as the lightweight design target, changing the piston rod to the hollow structure with the idea of structure optimization, the hollow piston rod geometry model is built with Creo threedimensional modeling software, and the topology optimization is carried out with Tosca optimization module in ABAQUS, and the optimal model parameters are obtained. The results of finite element analysis show that the total deformation of hollow piston rod is small, and the maximum distortion occurs at the port location, with a value of 0.138 mm. The maximum stress occurs at the piston rodpiston connection, with a maximum value of 342.18 MPa. Within the allowable stress range, it meets the requirements of lightweight design. The lightweight design of the piston rod reduces the quality by about 22.85%, the result is obvious.
