摘要：

Calculation of expected structural noise and vibration protection parameters require awareness of real dynamic properties of advanced engine design and airframe within wide frequency band of power unit vibration effect (10 to 500 Hz). On the base a package of obtained characteristics (frequency characteristics of dynamic compliance and function of vibro-acoustic conductivity of engine bodies and airframes) dynamic model of "Engine-Mount-Airframe" system is proposed on which grounds following algorithms were developed: estimation of levels of dynamic effect upon airframe caused by engine vibrations; calculation of expected structural noise in cabin and choice parameters of vibro-isolation attachments.
