                                        壽命試驗的要點有哪些,你清楚嗎?

                                        2017-12-29 0

                                        壽命試驗是驗證產品在規定條件下,處于工作(使用)狀態或貯存狀態時,其壽命到底有多長的試驗。有時也稱為疲勞試驗或耐久性試驗。 

                                        901.jpg

                                        壽命試驗的工程應用要點有四個: 

                                        902.jpg

                                        第一點:產品壽命試驗是一項周期長,需要較多投入的工作。因此,研發過程中,應對所選擇的配套產品進行重要性分析,對于影響系統使用安全和嚴重影響任務完成的產品開展壽命試驗;

                                        第二點:壽命試驗考核的是產品的壽命指標,而不是產品的保證期。產品保證期是承制方對其產品實行包修或包換的責任期限,不應與產品的壽命混為一談;

                                        第三點:當前有相當多的產品,制定其壽命試驗條件的依據不足,壽命試驗量值過高或過低,均可能導致壽命試驗達不到預期目的。因此,應加強根據產品的壽命剖面,科學、合理地確定產品壽命試驗剖面的研究;

                                        第四點:目前加速壽命試驗得到人們的高度重視,但要合理地選擇加速的應力、建立準確的物理化學模型,現仍處于研究階段。實際應用時應進行權衡分析,開展專項評審,慎重開展工作。
