Determining working ability for THACO HD 72 trucks under towing and gripping conditions when transporting goods in the northern mountainous rural area

Abstract

This paper presents the results of building a model to calculate the capacity of traction and adhesionof Thaco HD72 trucks when transporting goods on rural roads in the northern mountainous region. Applying automobile theory to build an expression to determine the necessary total weight of the vehicle to meet the conditions of traction and adhension to ensure the vehicle's movement on road. Based on that, the total weight of the vehicle can be calculated according to the traction and adhesion conditions on a number of different types of roads (asphalt, concrete surface, dry and wet dirty roads...) with the longitudinal slope of the road from 0⁰ to 15⁰ degrees with different transmissions of the gear box. The results obtained will be the basis for determining the vehicle's ability to work in specific terrain conditions as well as helping the driver choose the right gear and carrying load in accordance with the actual conditions.
