Abstract:

The study of vibrations of a self-propelled vehicle is made with the help of simplified dynamic models with a degree of freedom determined by the allowed degree of freedom existing between various subassemblies. This paper is a commentary of the analysis referring to the measurement of vertical accelerations for non-suspended masses (wheels), frame joint, cabin floor or seat, as well as vehicle translation speeds and accelerations for various types of roads, road excitation being an random stochastic process. Dynamic performance and car comfort are determined by the quality of the drive, breaking, and operation systems. Longitudinal accelerations are dynamic characteristics while speed and the impulse (impact force) developed during work determine the tensile strength of the car. For modern loaders, these values are measured by sensors which are limiting the engine drive operation, as well as the functioning of the drive system, thus ensuring an optimal functioning of the entire vehicle.
