Numerical Simulation of Limiting States of Self-Propelled Boom Cranes

There are significant difficulties in conducting practical studies of the limiting states of self-propelled boom cranes, therefore it is advisable to use computer simulation with specialist Simulation and Motion functions of the CAD software SolidWorks and MATLAB. A technique is developed for the numerical simulation of limiting states of a technical object on the basis of wavelet analysis of oscillatory processes of structural elements under non-normalized loading. The technique for the numerical simulation of the limiting states of a technical object consists of the following sequential actions: geometric modeling of the object, determining the rigidity properties of the structure, performing experiments on the technical object and the numerical model, processing the oscillation process data, and bringing dynamic properties of the virtual model in line with the prototype by obtaining convergence of their oscillatory processes. In order to finetune the developed technique, research on the physical prototype was performed. The results obtained provide an opportunity to conduct further numerical experiments on a virtual model of a technical object.
