Abstract: |
An accelerated storage scheme was formulated up by a sealing diaphragm material property and failure mechanism. An accelerated storage test study for a servo turbo-pump inlet sealing diaphragm was carried out in accordance with related theory model and method based on accelerated storage and life distribution. The test validated the quota parameter of sealing diaphragm storage period and obtained evaluating result based on the storage life and storage reliability of the diaphragm assembly. |
