Abstract
Results of working out of numerical model and data of a computational estimation of characteristics of random vibration of aeronautical engineering articles in the conditions of joint flight with the carrier are presented. Dependences for spectral characteristics and vibrational acceleration levels in various points of an article’s structure are received and zones of maximum levels of vibration for the articles placed on an external suspension of the maneuverable carrier are defined. Results of numerical experiments are compared by use of article’s dynamic models with various levels of complexity.Keywords:
