Abstract: As one of the core systems of modern special vehicles,the transmission system is a complex system engineering and has a key influence on the vehicle mobility performance. Accurate and complete design requirements are helpful to control the design risks,and reduce the development cycle and cost,etc.The model-based systems engineering method is applied to the requirement analysis process of transmission system,and a method characterized by development stages and structure levels is proposed. Based on vehicle operating scenarios,the proposed method is used to capture the requirements of the transmission system and its components related to the vehicle performancefrom top to bottom,and defines the decomposition and traceability relationship among the requirements of the vehicle,the transmission system and its components. With system modeling language and related tools,this method is used to analyze the indicator-kind requirement of a special vehicle, and obtain the requirement indicators and the cross-linking relationships of different system levels in the whole stage of research and development The result shows that the ptoposed method can well build a set of requirement indicators of the transmission system,thus providing a direction for the performance matching and optimization analysis of the vehicle.
