Abstract The traditional wind tunnel strain balance design cycle is a manual iterative process. With the experience and intuition of the designer, one solution that meets the design requirements can be selected among a small number of design solutions. This paper introduces a novel software integration-based automatic balance design optimization system (ABDOS) and its implementation by integrating professional design knowledge and experience, stepwise optimization strategy, CAD-CAE software, self-developed scripts and tools. The proposed two-step optimization strategy includes the analytical design process (ADP) and the finite element method design process (FEDP). The built-in optimization algorithm drives the design variables change and searches for the optimal structure combination meeting the design objectives. The client-server based network architecture enables local lightweight design input, task management, and result output. The high-performance server combines all design resources to perform all the solution calculations. The development of more than 10 balances that have been completed and a case study show that this method and platform significantly reduce the time for design evaluation and design-analysis-redesign cycles, assisting designers to comprehensively evaluate and improve the performance of the balance.

基于软件集成的自动应变平衡设计优化方法与实现

摘要 传统的风洞应变平衡设计周期是一个人工迭代的过程。凭借设计师的经验和直觉，可以在少数设计方案中选择一个满足设计要求的方案。本文介绍了一种新型的基于软件集成的自动平衡设计优化系统（ABDOS）及其实现，它结合了专业的设计知识和经验、逐步优化策略、CAD-CAE软件、自主开发的脚本和工具。提出的两步优化策略包括分析设计过程（ADP）和有限元方法设计过程（FEDP）。内置优化算法驱动设计变量变化，寻找满足设计目标的最优结构组合。基于客户端-服务器的网络架构支持本地轻量级设计输入、任务管理和结果输出。高性能服务器结合所有设计资源来执行所有解决方案计算。已经完成的10多台天平的开发和案例研究表明，该方法和平台显着减少了设计评估和设计-分析-重新设计周期的时间，帮助设计人员全面评估和改进天平的性能。
