Effects of Tank Shape on the Roll Dynamic Response of a Partly Filled Tank Vehicle

摘要

The directional response and roll stability characteristics of a partly filled tractor-semitrailer vehicle, equipped with various cross-section tanks, are investigated as functions of fill volume and steer inputs. The tank-vehicle combination is analytically modeled upon integrating a quasi-static roll plane model of a partly filled tank of generic cross-section with a three dimensional directional dynamic model of a five-axle tractor-semitrailer vehicle, assuming constant forward speed.
