| Abstract: |
| The jet-pipe servovalve is widely used in the fields of aeronautics and astronautics;it is a kind of typical two-stage flow control electro-hydraulic servo-valve,whose performance will degradate due to work loads and environmental loads in practical use.The structure and working principle of jet-pipe servo-valve are introduced,the failure mechanism of weak item affecting jet-pipe serv-valve durability is analysed, the software simulation is conducted and the durability lifetime is calculated.The weak item's durability lives of the jet-pipe servo-valve are obtained with software simulation and theoretical calculation respectively.The results and their analysis show preliminarily that the jet-pipe servo-valve durability life meets its standard requirements.Software simulation and durability life calculation method can be used to predict similar durability lifetime and evaluate product's durability level;this,we believe,is useful for improving product's durability design. |
