Tsybulnyk S. Improvement of means of functional diagnostics and protection of tanks on the basis of simulation

Thesis is devoted to the improvement of functional diagnostics systems by integrat-ing into them elements of simulation modeling for predicting changes in technical state of constructions. Thesis is also devoted to the development of protection means for objects used for storage of environmentally hazardous substances and operated in remote locations under the influence of natural and anthropogenic disturbances or wind load. A geometric modeling and tank simulation were done to evaluate the impact of its design elements on the change in the wind load distribution. The functional dependence of the maximum pressure on the walls of tank depending on the speed of air flow was estab-lished. Geometric models of wind load protection means for tanks were developed. The efficiency of the developed means of protection for tanks with ground and underground foundations was researched. General functional diagram of the automated system of functional diagnostics was designed. Visualization subsystem and its information model were developed. Visualiza-tion subsystem consists of two main modules - vibration signal processing module and simulation. Algorithms and software for visualization of the results of vibration measure-ments, inclination angles and, stress and plastic deformation prediction were developed for visualization subsystem. Adequacy of simulation models was proved.
