同步发电机组的抗冲击动力学分析 施建荣 (海军标准规范研究所，上海200235) 摘 要：舰船冲击环境主要是水下爆炸、武器直接命中、自身发射武器爆炸翻梭爆炸冲击渡作用于船体的结 果。它的传递特性是位移、速度、加速度和持续时间。舰船装备的坑冲击考核目前有冲击试验、静力学分析、 动力学分析和冲击试验与动力学分析的组合4种方法。舰船装备进行抗冲击考核的目的是检验战时环境下装备 承受上述冲击载荷的能力O论述T同步发电枫组的抗冲击动力学分析以及这种分析隽_法的优点和局限性。 关键词：舰船：同步发电机组；动力学分析 On Shock ResistingHighImpactDynamicsAnalysis for GeneratorSet Synchronization Shipboard SHI Jian——rong Research (StandardizationInstitute，Naval 200235，China) EquipmentAcademe，Shanghai be toshock non—contactunderwater Abstract：Navyshipsmay subject generatedby weapon hits，self—delivered andnuclearblast．Theshock explosion，contactweapon weaponexplosion environmentisthe resultofnon—contact ornuclearblast physical explosion，contactexplosion which andaccelerationtothe structure．The impartrapiddisplacement，velocity ship highimpact meanshavefour for test，static testing typesshipboardequipment：shockanalysis，dynamics andstatic combinedwith of analysis analysis dynamicsanalysis．Thepurposehighimpacttesting for is the of towithstandshock to installations shipboard verify abilityshipboard equipment beincurred wartimeserviceduetotheeffectsofnuclearor loadings，which during may conventional
