Abstract


The research objective presented in this paper is working out the mathematic model and methods of computer modeling the performance of hydraulic loader cranes with excessive backlashes in sections hinge joints. The mechanism for generating the additional impact load in joints is illustrated. It is based on analyzing the hinge pin displacement within the backlash and its periodic collisions with the limiting elements of a hinge joint. This method allows evaluating the degree of influence of the backlash value on the changes in the qualitative characteristics of the dynamic load of the cranes metal structure and the motion parameters of the conveying load.  The computer modeling of the loader crane dynamics in its turning motion was performed. The excessive backlash at the point of connection of a load-handling device and a boom was analyzed. The comparative evaluation of the dynamic load of the crane metal structure was performed for two controlling cases: 1) the absence of a backlash; 2) the presence of a backlash (the backlash variation range is 0…2 mm). While the crane is in operation, some excessive backlashes may result in increasing the dynamic load of loader cranes metal structure twofold and more.
