TL;DR: In this article, the dynamic characteristics of a catenary system using the finite element method (FEM) and dynamic modelling for developing a suitable pantograph at high speed is analyzed. But the analysis of the catenary is limited to a beam model.

TL;DR: In this paper, the analysis of the catenary based on the finite element method (FEM) is performed to develop the pantograph and state sensitivity analysis is executed with respect to design variables considered by the system.

TL;DR: In this paper, a sensitivity analysis of a front wheel steering vehicle in the time domain is considered, where a two-degree-of-freedom bicycle model is used to display the simplest lateral dynamic effect and is useful for understanding the dynamic characteristics and control aspects of the target system.

TL;DR: In this article, a simple and new representation of mechanical joints by using vector bond graph elements is provided, where the power is conserved and the law of energy conservation is reserved through all elements.

TL;DR: In this paper, the sensitivity analysis of yaw rate for a front wheel steering vehicle is performed in the frequency domain, where a two degree of freedom system is used to represent a simple vehicle model in order to derive the system transfer function.
