Aiming at the problem of weak simulation capability of the system design models described formally in model-based system engineering, by applying the meta-model transformation method, this paper presents a visual method of transforming system design models to executable simulation model based on SysML. According to the characteristics of model transformation, two transformation meta-models, transformation rules and trans-formation activities, are defined abstractly based on SysML and its extension mechanism. The mapping relation-ships between design meta-model and simulation meta-model are established firstly, and then the visual transfor-mation of the system design-simulation models is achieved by instantiating the transformation meta-model to re-duce the complexity of the model transformation. Finally, a case of simple mechanical system is used to verify the feasibility of the proposed method.%针对基于模型的系统工程中形式化描述的系统设计模型仿真能力不足的问题，结合元模型的转换思想，提出一种基于 SysML 的可视化模型转换方法，将系统设计模型转换为可执行的仿真模型。根据模型转换特点，抽象定义基于SysML语言及其扩展机制的转换规则和转换活动等2种转换元模型。在构建设计-仿真元模型映射关系的基础上，通过转换元模型的实例化对系统设计-仿真模型实现可视化转换，以降低模型转换的复杂性。最后以简单机械系统为例，验证了该方法的可行性。
