Analysis of the Directional Response Characteristics of Double Tankers 781064

A linear mathematical model is developed for studying the directional response and yaw stability of many-axled, multi-articulated tanker trucks. Analytical results obtained from the model provide an understanding of (1) the factors leading to unstable lateral responses of double tankers when only the rear compartment of the rear (pup) trailer is loaded and (2) the likelihood of rollover of the pup trailer in obstacle-avoidance maneuvers on the highway.
Rigidizing the connection at the pintle hook is found to improve the directional performance of the double tanker.
