Abstract: To enhance the reuse of analysis geometrical models and analysis knowledge, a component-based analysis technique for complex product digital prototyping was put forward, which regarded the analysis unit as an uniform mechanism of description, definition and basic organization for analysis model and knowledge, and analysis tree was used as sub-structure and correlation of analysis. Based on analyzing hierarchy of complex product, hierarchical information modeling and component-based analysis modeling were constructed, which was the basic mechanism of information organization and processing. Realization techniques of component-based analysis were studied, including the process of component-based analysis, establishment of information model, key parameter identification and performance range constraint. Finally, realization of componentbased analysis technology was introduced in detail by taking the analysis of hydro-electric generating units as an example.
