请教：振动，冲击和碰撞三者的区别？

振动讲究持续性，疲劳性 冲击是瞬间性，破坏性！ 碰撞是重复性的冲击 选择做什么测试，嘿嘿，超出我个人能力了 应是从生产到出货后到客户端将会出现什么情况吧，一整个过程按理说，振动冲击碰撞现象都是存在的 都做当然最好哇。嘿嘿哈 参考行业标准吧

如果客户没有特别要求做哪项实验， 那就按行业标准来做吧， 标准里通常会列出需要做哪些机械类实验的．

我们在做测试的时候也是模拟现实使用过程中的某些情况 那三者分别模拟的是使用过程或搬运过程中的哪些情况呢？ 谢谢

振动测试： 包装振动－模拟产品运输过程中可能会发生的振动（比如汽车、飞机、轮船等各种运输方式），通常标准里有不同运输方式的振动要求 Operation振动－模拟产品使用过程中会遇到的振动，各种产品的次项测试应该有不同要求。 [url=http://www.kekaoxing.com/club/thread-2858-1-1.html]MIL-STD-810F[/url]中对振动的描述： Configurethetestitemappropriatelyforthelifecyclephasetobesimulated. a.Transportation.Configurethetestitemforshipmentincludingprotectivecases,devices,and/orpacking.Mountthetestitemtothetestfixture(s)bymeansofrestraintsand/ortie-downsdynamicallyrepresentativeoflifecycletransportationevents. b.Operationalservice.Configurethetestitemforserviceuse.Securethetestitemtothetestfixture(s)atthemountingpoint(s)andusethesametypeofmountinghardwareasusedduringlifecycleoperationalservice.Provideallmechanical,electrical,hydraulic,pneumaticorotherconnectionstothematerielthatwillbeusedinoperationalservice.Ensuretheseconnectionsdynamicallysimulatetheserviceconnectionsandthattheyarefullyfunctionalunlessotherwisespecified. 810F中对冲击（Shock）的描述： a.ProcedureI-FunctionalShock.ProcedureIisintendedtotestmateriel(includingmechanical, electrical,hydraulic,andelectronic)initsfunctionalmodeandtoassessthephysicalintegrity,continuity andfunctionalityofthematerieltoshock.Ingeneral,thematerielisrequiredtofunctionduringthe shockandtosurvivewithoutdamagetoshocksrepresentativeofthosethatmaybeencounteredduring operationalservice. b.ProcedureII-Materieltobepackaged.ProcedureIIistobeusedwhenmaterielwillrequireashipping container.Itspecifiesaminimumcriticalshockresistanceleveltoahandlingdropheight.Theshock definitionmaybefurnishedtoapackagedesignerasadesigncriterion.Thisprocedureisnotintended forthetestofextremelyfragilemateriel,e.g.,missileguidancesystems,precision-alignedtestequipment, gyros,inertialguidanceplatforms,etc.Forextremelyfragilematerielwherequantificationofshock resistanceisrequiredProcedureIIIshouldbeconsidered.Seeparagraph2.3belowforprocessing techniquesusefulinexpressingshockresistancecriteria. c.ProcedureIII-Fragility.ProcedureIIIisusedtodetermineamateriel’sruggednessorfragilitysothat packagingcanbedesignedforthemateriel,orsothematerielcanberedesignedtomeettransportation and/orhandlingrequirements.Thisprocedureisusedtodeterminethecriticalshockconditionsatwhich thereisreasonablechanceofstructuraland/orfunctionalsystemdegradation.Toachievethemost realisticcriteria,performtheprocedureatenvironmentaltemperatureextremes.Seeparagraph2.3below forprocessingtechniquesusefulinexpressingshockfragilitycriteria. d.ProcedureIV-TransitDrop.ProcedureIVisintendedformaterieleitheroutsideoforwithinitstransit orcombinationcase,oraspreparedforfielduse(carriedtoacombatsituationbyman,truck,rail,etc.).

谢谢各位的指点！ :):):victory:

如果客户没有要求，你想提高自己产品的可靠性，可以找到标准，然后做的更严酷一些。做与不做就看自己对产品品质的要求高不高了。

测试物检测方法:一.将测试物放在手上,以最快速度上下移动.震动测试完毕. 二.将测试物放在手上,人从2米高地方跳下,手姿势保持不变,冲击实验完毕. 三.将测试物放在手上,以最快速度撞击墙壁,碰撞测试完毕. 结果: 个人:因纯天然绿色测试,无需资金和损耗,被公司嘉奖. 公司:因产品屡次通过天然测试,而大量生产,被大量退货.倒闭!

呵呵，个人:因纯天然绿色测试,无需资金和损耗,被公司嘉奖. 公司:因产品屡次通过天然测试,而大量生产,被大量退货.倒闭!

哈哈哈哈

一般都是模拟现实使用中可能会遇到的状况，产品的标准一般会有，可以参考
