Abstract

Реалізована система автоматизованого проектування побудови моделі пневматичної шини з урахуванням її внутрішньої багатошарової будови. Створена інформаційна система, яка будує шину, розраховує напружено-деформований стан, похибку та виводить результати. Користувач має можливість перевірити параметри за допомогою креслеників, побудованого у SolidWorks. У якості прикладу побудовано та розраховано дві моделі: автомобільної та велосипедної шин.In this work there is a project of working out of the information system of automated constructing of computer models of pneumatic tires. Using of CAD facilitates model constructing and rais es a precision of the calculation, makes it possible to vary by parameters for the attainment of a reduction of the expense value, the augmentation of a using term, the reduction of consumptions during the exploitation. There is a need for the creation of specialized CAD, which will take into consideration a specific nature of the object, which is researched; will get necessary characteristics in the practical ratio by the direct application, will have an interface which will be simple convenient and clear intuitively for the designer as well. The system allows to take into account inset multilayered struture of tire and gives geometric and finite-element model, which could be used for analysis of its deformed state. A structural analysis is also automated and organized via the CAE software. The user has the possibility to check the necessary parameters using drawings, built in SolidWorks and to get figures of a distribution of the stresses and strains and to get the model error estimation. In spite of essential differences in measurements, the definite variation of inside structure, all pneumatic tires have general principles of the geometric design, that makes it possible to create a common system of the parameterization and automated constructing. Different rubber mixtures and composite materials are used in each layer of the pneumatic tire. So, the setting procedure of unique features of materials of the layers will be carried out for each one. In this work a main attention is given to parametric modeling of a tire profile and its structure. As an example two model is built and designed. These are the models of automobile and bicycle tires
