摘要

Methods and devices for determining the stiffness of bellows type joints involved based on models ".The system provides the answers to frequ00b3u00eancia natural (132) in subsystems of the tube (10) including bellows type joints involved (12).The system determines the multiplier of rigidity from the values of input (110) and uses the factor of flexibility determined to determine the responses of frequ00b3u00eancia natural.The input values include contributions to geometry (116) and the entries of the dynamic operational conditions (114). The factor of flexibility is determined by a regression equation.The regression equation, based on the testing data of dynamic stiffness of various configurations for joints bellows type involved.Allows the system to characterize the bellows type joints involved using a geometry element that includes a factor of flexibility given based on data of testing dynamic stiffness.
