基于有限元方法的轨道吊结构设计优化

Structural Design Optimization of Track Crane Based on the Finite Element Method

基于最优化设计概念,运用通用有限元软件ANSYS的结构优化功能,以轨道吊主梁为优化对象,建立完整三维结构模型,以结构设计关注的主梁翼缘板、腹板几何尺寸为输入参数,以结构强度、刚度、稳定性为响应参数,在起重机设计规范允许范围内,通过分析获得结构最优化模型。结果表明:结构设计优化可合理利用结构部件承载能力、控制结构重量,在满足结构设计合理、安全的前提下,实现产品精益制造,较大地提高企业经济效益。

Optimized design based on the concept of this paper, the finite element software ANSYS structural optimization features to track objects in order to optimize the girder crane, build a complete three-dimensional structural model to design concerns girder flange plate, web geometry as an input parameter to structural strength, stiffness, stability of response parameters in crane design specification within the allowable range, obtained by analyzing the structure opti- mization model. The results show that： the structural design optimization of structural components can reasonably use the carrying capacity, weight control structures, to meet the reasonable structure design, safety premise of achieving lean manufacturing products, greatly improve the economic efficiency of enterprises.
