中文摘要:
      目的 研究某新型结构导弹包装箱的动力学特性。方法 利用有限元分析方法对导弹包装箱进行模态分析和随机振动分析。结果 得到了导弹包装箱的固有频率和振型,以及结构在随机载荷作用下的动力学响应结果,导弹包装箱的前6阶固有频率分布在13~44 Hz范围内,在随机载荷的作用下,导弹包装箱3个方向的最大应力分别为97.6,149.3,151.1 MPa。根据导弹包装箱的动响应结果确定了箱体在随机振动环境下的危险部位。结论 在路面随机载荷作用下,箱体的整体结构满足设计要求,为导弹包装系统的设计和校核提供了依据。
英文摘要:
      The paper aims to study the dynamic characteristics of a new structure missile package. The finite element analysis method was used to analyze the modal and random vibration. The natural frequency and vibration mode of the missile package and the dynamic response results of the structure under random load were obtained. The first 6 natural frequencies of the missile packing cases were distributed within the range of 13~44 Hz. Under the action of random loads, the maximum stresses in the three directions of the missile packing cases were 97.6 MPa, 149.3 MPa, and 151.1 MPa. According to the dynamic response of the mis-sile box, the dangerous parts of the box under random vibration environment were determined. The overall structure meets the design requirements under the random road loading. It provides a basis for design and verification of the missile packaging system.
