Dynamic Modelling of a Hydraulic Engine Mount Including the Effects of Elastomer Aging

In this article, the effect of material aging of an elastomeric main spring (MS) inside a hydraulic engine mount (HEM) on its dynamic performance is investigated. A set of HEMs aged under realistic operational conditions are used to create an empirical material aging model of the elastomer at two different temperatures (35°C and 95°C) using dynamic mechanical thermal analysis (DMTA).

A short note on equal peak design for the pendulum tuned mass dampers

By: A. Deraemaeker and Payam Soltani
Abstract:
Pendulum tuned mass dampers (PTMDs) are used to passively mitigate the vibrations of tall structures and buildings. The main objective of this short note is to introduce analytical formulae for the optimum design of the linear PTMD coupled to an undamped primary system. Den Hartog's equal peak method is applied to derive the optimum design. With the mass ratio between the primary system and the PTMD, the optimum length and optimum damping of the pendulum are calculated. The formulae are presented in both dimensional and non-dimensional forms and are simple to apply in real applications. It is also shown that the vibration mitigation performance of the proposed optimum design precisely matches the results obtained by numerical optimisation techniques.

Nonlinear free and forced vibration analysis of a single-walled carbon nanotube using shell model

 By :Payam SOLTANI, J SABERIAN, R BAHRAMIAN, A FARSHIDIANFAR

In this Paper, the nonlinear free and force vibration of a single-walled carbon nanotube (SWCNT) with simply supported ends is 

investigated based on von Karman’s geometric nonlinearity. The SWCNT described as an individual shell and the Donnell’s 

equations of cylindrical shells are used to obtain the governing equations. The Galerkin's procedure is used to discretized partial
