摘要
为满足排管机立柱的轻量化设计要求,快速实现设备的降本增效,以排管机立柱截面尺寸优化为研究重点,利用Design Modeler模块进行参数化建模,利用ANSYS Workbench软件静力学模块对立柱的刚度、强度以及振动模态进行有限元分析,并对立柱的结构参数进行优化。分析结果表明:立柱侧壁板宽度L_2和折弯板角度α对最大总变形的敏感度最高,增大L_2和α的数值可以有效减小最大总变形量; L_2和α对最大等效应力的影响是非线性的,随着α的增大,最大等效应力先升高后降低,L_2增大时最大等效应力会降低;优化方案相较原方案质量减轻3. 2%,最大总变形量降低14. 1%,在最大等效应力降低的同时前3阶固有频率均有所提高,达到了减轻立柱质量、增强刚度及提高固有频率的优化目的。所得结果可为类似机械设备的尺寸优化设计提供借鉴与参考。
To meet the lightweight design requirements of the pipe racking column, and quickly realize cost reduction and efficiency increasing of the equipment, the optimization of the pipe racking column section dimension is taken as the research focus. The design modeler module is used for parametric modeling, and the statics module of ANSYS Workbench software is used for finite element analysis on the stiffness, strength and vibration modes of the column.Then, the structural parameters of the column are optimized. The analysis results show that the width of the side wall of the column L 2 and the angle of the bending plate α are the most sensitive to the maximum total deformation. Increasing the values of L 2 and α can effectively reduce the maximum total deformation. The influence of L 2 and α on the maximum equivalent stress is nonlinear. The maximum equivalent stress increases first and then decreases with the increase of α. The maximum equivalent stress decreases with L 2. The optimized scheme reduces the mass by 3.2% and the maximum total deformation by 14.1%. When the maximum equivalent stress is reduced, the natural frequencies of the first 3rd order are improved, and the optimization purpose of reducing the column quality, enhancing the stiffness and improving the natural frequency is achieved. The obtained results can provide references for the dimension optimization of relevant equipment.
