Abstract: | Self-propelled transport vehicles of articulate bucket type for constructions include loaders or automated dumpers for sites, with buckets for ground transport. This paper presents the calculation of the fatigue interval for the moving element of the selfpropelled vehicle with tires, considered as an in line vibration system, and the working functions are represented by the micro-profile of the road (stationary ergodic processes). A relationship is stressed out between dynamic processes and structural stresses determined by these processes during the work. The spectrum vibration theory allows, once the mechanism working character is known, a complete arrangement of dynamic tension distribution places. The calculation method for the fatigue interval, in the case of vehicle parts, is based on the cumulative fatigue defects theory. With these details in mind, the “narrow band” type process is determined. |
