摘　　要：飞行器动力学建模中采用面向对象的设计样式,可极大提高动力学建模的水平和效率。本文探讨了手柄本体样式、容器样式、通用积分样式、层次聚合样式等在动力学建模中的应用,并给出了具体实例。其中,通用积分样式和层次聚合样式是针对飞行器动力学建模的特点由本文新提出的。通用积分样式是动力学建模的基础架构,可提供积分右函数与系统状态计算的分离以及积分方法选取与右函数的分离,增强了系统开发的灵活性。层次聚合样式通过在类体系的不同层次采用不同的聚合方式,为灵活性与方便性的不同取舍提供了支持。本文的工作验证了设计样式在动力学建模领域应用的有效性。It can improve modeling level and efficiency adopting object-oriented design pattern in vehicle dynamics modeling. Four patterns are discussed in the paper, including handle-body pattern, container, common integral pattern and hierarchy aggregation pattern. Some examples are given. In these four patterns, common integral pattern and hierarchy aggregation pattern are put forward in this paper for the first time. Common integral pattern is the basic architecture in dynamics modeling, which can separate integrand from system state calculation and separate integration from integrand. By employing this pattern, it can be more flexible to develop application. Hierarchy aggregation pattern can provide the balance in agility and convenience by using different aggregation style in different hierarchy. The paper shows that it is effective to use design pattern in dynamics modeling.
