摘　　要：为建立逼真的三维模型,在STK(卫星工具包)软件中进行任务仿真,讨论了直接获取mdl格式模型、编写mdl文件、转换模型等3种STK模型制作方法,并对这几种制作方法的优缺点进行了分析。针对不同制作方法带来的模型问题,重点探讨了组件层次调整、形状修改、显示效果优化、动作关节优化、特效设置等5种mdl格式模型优化方法。通过实例说明5种优化方法的优化效果,结果表明相关方法能有效地优化模型。To build vivid 3D models for mission simulation with STK （Satellite Toolkit）, the paper firstly discusses three types of modeling methods featuring direct access of mdl models, mdl files writing and format transforming from other types. Then, it analyzes both the advantages and disadvantages of these methods. To solve problems caused by the above methods, five optimization approaches, namely, adjustment of the hierarchy of components, model shape modification, display effect optimization, model articulation optimization and setting of model special effects, are discussed. Examples are provided at the end of the paper to show the effectiveness of the proposed approaches.
