- Abstract
Objective:To investigate the opened form and the fractured pressure of pulse separation device in double pulse motor.Methods:set up a three-dimensional finite element model of PSD,put forward the calculation for stress intensity faetor of prefab notch,simulated the fractured form of PSD,grained the fractured opened.Results:The three-dimensional finite element model of PSD objectively reflected the real fractured form of PSD,and the calculation fractured pressure was in accord with tests well.Conclusion:The built three-dimensional finite element model is reliable to analysis the opened form and calculate the fractured pressure of PSD,and the research method is useful for designing double pulse motor configuration.
