摘要
针对飞机总体设计阶段重量重心(c.g.)估算的专业要求、设计方案反复调整的特点,提出了基于三维参数化建模的重量重心快速估算方法,从而实现后续的快速参数化调整。基于该方法的分析流程,通过分析飞机外形建模和结构、系统重量建模的工作对象和专业逻辑,对各个重量组成及其建模过程进行了参数化描述和流程定义,用于指导完成整个设计分析系统的开发实现。最后,通过算例演示了基于三维参数化建模进行重量重心快速估算的步骤。
According to the requirements of frequent estimation and adjustment of weight and center of gravity （c. g. ） during aircraft conceptual design, a method based on 3-D parametric modeling is proposed to realize rapid weight and c. g. estimation and adjustment by editing relevant parameters. Based on the method, the parameters used to describe the model and the process of modeling are determined by analyzing the object and logic of aircraft modeling, so that the system used for model design and weight analysis can be developed. Finally, a case study is presented to show the procedure of weight and c.g. estimation using the method proposed by this paper.
