借助飞行器表面气动噪声环境特性的工程估算公式,考察了某飞行器结构在气动噪声激励下的响应的计算问题。气动噪声激励是作用于飞行器外表面的分布随机载荷,是具有一定空间相关性的。因此,在计算结构响应时,气动噪声激励的空间相关性是不能忽略的。计算结果表明,将气动噪声的空间相关性考虑到计算中能更精确地预测飞行器气动噪声环境下的随机振动响应。 With the engineering estimation formula of aerodynamic noise environment on aircraft surface, the calculation of the response of an aircraft structure under aerodynamic noise excitation was investigated. Aerodynamic noise excitation is a distributed random load acting on the outer surface of the aircraft, which is of certain spatial correlation. Therefore, the spatial correlation of aerodynamic noise excitation can not be neglected in the calculation of structural response. The calculation results show that the spatial correlation of aerodynamic noise can be considered in the calculation to predict the random vibration response more accurately under aerodynamic noise environment.
