In structural–acoustic coupled analysis, the finite-element method in which the acoustic space is described by sound pressure and the structure is described by displacement is often used. However, the eigenvalue analysis in that method takes a great deal of computational time because the mass and...
(1993), where fluctuations in the fundamental period and amplitude are modeled well using a two-mass model (m1=1,n1=2) with a coupled mass on the superior surface of one side (m1=1,n1=3) to represent the pedunculated polyp. In spite of the relative success in modeling structural ...

[26]used it as inspiration to develop a spring–damper–mass model, called the coupled lumped mass (CLM)model, in order to more faithfully encompass the track/soil coupling. This paper presents the revisited model that builds upon [23],adding a CLM model, to improve the prediction of ...
Mooring line motions are based on the non-linear lumped mass method and are coupled to the floater by kinematic relations. The non-linear floater and mooring system coupled model has been validated with tank test results, and introduced in (Touzon et al., 1070). In the present work all no...

The modal characteristics of the transverse vibration of an axially moving roller chain coupled with lumped mass were analyzed.The chain system was modeled by using the multi-body dynamics theory and the governing equations were derived by means of Lagrange's equations.The effects of the parameters...
