On the basis of defining the risk conduction and risk coupling,the main risk conduction pattern in equipment development is offered. Based on CFD technology simulate two of the risk coupling pattern,the simulation results to analyze the risk coupling mechanism is combined. The said method has some stimulative effect in opening out risk conduction and coupling mechanism in equipment development,and it establishes good basis for the study on correlative relationship between key factor of risk conduction and coupling.
