【摘要】：导轨的变形是影响异型内腔曲面加工装置加工质量的主要因素之一,为降低导轨的最大挠度,提高工件的加工精度,提出了一种基于iSight多学科多目标设计优化软件环境下的导轨结构优化设计方法和仿真流程。为实现异型内腔曲面加工装置导轨结构的多目标优化设计,采用iSight和ANSYS参数化设计语言APDL创建一套导轨结构优化集成系统,并针对某异型内腔曲面加工装置的导轨,应用NLPQL序列二次规划算法对其结构进行优化。结果表明,导轨降低挠度效果明显,且实现了轻量化,优化结果合理,方法可行有效,在工程实际中具有较高的应用价值。
[Abstract]:The deformation of the guideway is one of the main factors that affect the machining quality of the curved surface machining device. In order to reduce the maximum deflection of the guideway and improve the machining accuracy of the workpiece. In this paper, an optimization design method and simulation flow of guideway structure based on iSight multi-disciplinary and multi-objective design optimization software environment are presented. In order to realize multi-objective optimization design of guideway structure for machining device with irregular inner cavity surface, this paper puts forward a method of optimization design of guideway structure based on iSight. . By using iSight and ANSYS parametric design language APDL, a guide rail structure optimization integration system is established, and the guide rail is designed for a curved surface machining device with a special-shaped inner cavity. The NLPQL sequential quadratic programming algorithm is used to optimize the structure. The results show that the deflection reduction of the guideway is obvious and the lightweight is realized. The optimization results are reasonable and the method is feasible and effective. It has high application value in engineering practice.
