摘　　要：依据膜片材料性能及产品失效模式,制订了膜片加速贮存试验方案。结合加速贮存和寿命分布相关理论模型和方法,对某型涡轮泵入口密封膜片组件进行加速贮存试验研究,验证了膜片组件贮存期的指标要求,并获取了膜片组件的贮存寿命与贮存可靠性的相关评估结果。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.
