摘要
传统的工程装备优化设计方法主要是依靠经验公式,而计算模型和公式的简化以及经验参数的选用,使得工程装备的优化设计变得保守且精度不高,难以满足装备不断发展的要求。为解决这一问题,将仿真技术引入到工程装备的优化设计中。首先介绍了仿真技术及其在工程装备优化设计中应用的意义,在此基础上,探讨了仿真技术应用于工程装备优化设计的范畴与思路,提出了基于仿真试验的工程装备优化设计方法。该方法有助于全面分析工程装备的结构力学与流体力学特性,为装备的优化设计提供更翔实可靠在依据;同时,也有助于缩短装备的设计周期,减少装备的设计费用。
The simplification of mathematics model and formula and the usage of safety margin develop conservatism and create errors in optimum design of engineering equipment. In order to solve this problem, the technology of numerical simulation is introduced to the design. Firstly, the history of simulation technology and its value applying to the optimum design of engineering equipment are discussed in this paper. Secondly, the category and thought way of applying simulation technology to optimum design are analyzed. After analysis of structure dynamics and flow field of engineering equipment, all kinds of performances will be optimized and the reliability of the equipments can be improved. This is important to shorten the design period and reduce the design expenses of engineering equipment.
