摘要
目的研究一种综合考虑陆上环境与舰船环境多应力下的舰载导弹弹上计算机加速寿命试验方法,能更具代表性和真实性地描述产品在综合环境条件下的环境应力,进而为环境应力剖面尽可能准确地折算为加速应力剖面奠定基础。通过加速寿命试验,将产品贮存时间加速至目标年限,验证与评估产品剩余贮存寿命。方法针对舰船工作环境条件,从搭载研究对象的舰船出海海况入手,利用海况与舰船振动量值的对应关系,确定舰船振动应力。结合考虑综合环境下的其他应力,研究出一种结合温度-振动-电应力等环境条件的加速试验方法,以已经达到设计贮存寿命期限的舰载导弹弹上计算机为试验对象,开展温度-振动-电应力综合加速寿命试验。结果通过运用温度-振动-电应力的加速寿命试验方法,验证和评估了某型舰载导弹弹上计算机具备延寿至目标年限的剩余贮存寿命,取得了良好的试验效果。结论根据舰船工作环境对贮存寿命的影响,针对性地研究了舰船振动加速试验,给出一个更加贴合实际寿命的寿命评估结果,为后续延寿研究工作提供了可靠依据。
This paper intends to study an accelerated life test method for shipborne missile board computer under the multi-stress of land environment and ship environment,which can describe the environmental stress of products under the com-prehensive environment more representatively and authentically,and thus lay a foundation for converting the environmental stress profile into the accelerated stress profile as accurately as possible.Through the accelerated life test,the product storage life is accelerated to the target lifetime to verify and evaluate the residual storage life of products.According to shipboard work-ing environment,and starting from the sea state of the ship carrying the research object,the vibration stress of the ship is deter-mined by the corresponding relationship between the sea state and the vibration magnitude of the ship.Considering other stresses under the comprehensive environment,an accelerated test method combining temperature-vibration-electrical stress and other environmental conditions is developed.Taking the shipborne missile board computers that have reached the designed storage life as the test objects to carry out a comprehensive accelerated life test of temperature-vibration-electrical stress.By us-ing the accelerated life test method combining temperature-vibration-electric stress,it was verified and evaluated that the resid-ual storage life of shipborne computers could be extended to target lifetime,and good test results were obtained.According to the influence of ship working environment on storage life,the study on vibration acceleration test of ship achieves a life evalua-tion result which is more suitable for the actual life,providing a reliable basis for the follow-up life extension research.
