1.引言像飞机所有外挂物一样,“捕鲸叉”导弹(AGM-84A)在其使用期限内将受到各种冲击和振动载荷的影响,这使导弹及其设备的可靠性受到威胁。与飞机作战直接有关的最重要的冲击和振动环境包括载机弹射和用拦阻装置着陆时的冲击载荷,挂飞时长期振动载荷,在飞机火炮射击时引起的短期振动载荷以及在导弹发射时强烈的冲击载荷。在较早的一个报告上评定了导弹结构对发射冲击的响应,本报告讲的是导弹对上面提到的其它动力载荷的响应。
1. INTRODUCTION Like all aircraft gunships, the “whaling fork” missiles (AGM-84A) are subject to various shock and vibration loads over their useful life, threatening the reliability of missiles and their equipment. The most important impact and vibrational environments directly related to aircraft operations include impact loads upon launch of the aircraft and landing with the arresting device, long-term vibrational loads at the time of launch, short-term vibrational loads caused during the firing of the aircraft artillery and intense Impact load. In an earlier report, the response of the missile structure to the launch impact was assessed and the report addresses the missile’s response to the other dynamic loads mentioned above.
