Virtual Prototype for Simulation and Analysis of Traction Systems in Interaction with Roads
MetadataShow full item record
This study deals with numerical simulation of an equipment with full hydrostatic driving system. Based on the clasical mathematical models - single degree of freedom and two degree of freedom models, it was developed a new set of practical simulation models, named SYMTRAX-I, respectivelly SYMTRAX-II, for the technological equipments with integral hydrostatic driving system. With the help of this models it was simulated the kinematic excitation phenomenon generated by the road. The complexity of this analysis consists in the fact that specific dynamic phenomenon appears at the interaction between the system framed from the road, tire wheels drive devices and the equipment insulated on the tire wheels, and the rolling system, with traction transmission and the base machine engine. This paper presents both SYMTRAX-I, and SYMTRAX-II virtual prototypes, the simulation hypothesis, the computational results, and the comparative analysis between the instrumental tests and the simulation results.
