Goal: to improve the technical level of hoisting and conveying equipment by improving structures machinery and modes of its use. Methods of research: theoretical research on mathematical models using mathematical package Maple, tabulared processor Excel, and others, experimental studies in laboratory settings using strain gauge instrumentation. Theoretical and practical results: 1.The mathematical model of process of welding with flux-cored wire, allowing to predict the quality of the weld. 2. Developed recommendations for the creation of devices to prevent the locking of the working body of earth-moving machines; 3. Developed experimental model crawler excavator. 4. The developed algorithm for power analysis of the crank-hinge mechanism shahania of the dragline. 5. Developed a methodology for improved methods for assessing the residual life of cranes with a view to their simplification and allowing them to perform at an engineering level. 6.Studies of load supporting elements jib cranes. Novelty: 1. Developed process model hardfacing cored wire. 2. The developed simulation model of the cutting processes of the soil taking into account the dynamic loads in the elements of the actuators of the excavator. 3. Developed generalized multibody mathematical model of the mechanism for lifting the overhead crane, takes into account the mutual influence of elements on the dynamic factor. 4. Developed a methodology for the assessment of residual life of cranes can be run on an engineering level. 5. The developed model four legged walking propulsion excavator with regard to force and kinematic factors. The effectiveness of implementation: based on the methods of mathematical modeling of the improvement of the technical level of the material handling and earthmoving machines in their design and modernization. Scope: engineering.
