Pick-up Truck and Trailer Gross Vehicle Weight Study 2019-01-1109
The objective of this paper is to evaluate the dynamic performance of pickup truck – trailer configurations, using CVSE (Commercial Vehicle Safety and Enforcement) performance measures. The vehicle configurations will be evaluated for static rollover threshold, load transfer ratio, rearward amplification, friction demand, lateral friction utilization, high speed, low speed and transient offtracking and three-point handling performance. These measures are based on definitions from Canada’s heavy vehicle weights and dimensions study. Payload weights and trailers with fifthwheels and pintle hooks will be selected based on the CVSE Policy, maximum towing capacity of each pickup truck, and their maximum drive axle loads. The main purpose of this analysis is to test the stability and controllability of these vehicle configurations in a virtual environment at both low and high speeds. TruckSim – a commercial software package that predicts the dynamic performance of multi-axle vehicles in complex scenarios- will be utilized in this study. This package has been extensively used by the industry to evaluate and validate various vehicle configurations.
