From Quasi-Static Calculation of an Aerial Tramway System to Traveling Cycle Time Optimization

Résumé

The present study aims at building a numerical model of a long-distance single span aerial tramway with non-symmetric tracks and anchored cables at extremities. From a modeling point of view, aerial cable transport system is a nonlinear time variant structure as cables and vehicles are moving. Hence, a first step before dynamics study is to analyze the system changes by a quasi-static procedure neglecting inertia effects of the movement. It provides information on parametric evolution relative to the cable length controlled by the driving bull-wheel located at the bottom station. Results from static and quasi-static calculation are compared with experimental data measured on the real and unknown parameters are introduced in order to account for the lack of knowledge about cable length depending on several parameters as temperature, wear, permanent elongation, shortening operation etc. Identification of the correction parameters allows to update the model for a better fidelity. Finally, calculation results are applied to design acceleration and braking control curve of the moving cable in order to reduce the traveling time and increase system efficiency.
