The aim is to introduce students to the understanding of space and geometric forms in 3D environment. Intention is also understanding the topology types of machine parts, such as methodology of forming a 3D model as a starting point for the development of forms of machine parts and assemblies. Machine components shape and dimensions determination used to be conducted based on previous knowledge and overpowered skills from Machine elements 1 and 2 courses. Learning and exercising of procedures and tools developed for manipulating forms and dimensions with parameter changes. Aim od this modification is to get an optimum shape that allow us to achieve optimal solutions in machine design modeling.
Starting from basics in Machine elements, student used to define shape design of machine components concerning their dimensions and function. Taking into account other design criteria, student has skills to manage corresponding shapes of common machine components using CATIA software. It is completely trained to parametrically vary the shape and form parts, to optimize the form and combine them to compose the assembly. Student has acquired knowledge that the application of CATIA tool optimizes the shape and adjust the properties of this form. The student is also familiar with basics of using modules for simulation and structural analysis.
Introduction, on the course and shape modeling (concept model, role models, use of models). Modeling tools, for software and their characteristics. Principles and method of modeling the form. Surface modeling, surface models. Modeling geometric body (Boolean operations). Additional tools for modeling shapes in CATIA V5. Forming of machine components shape based on dimensions and their functional determination. Overview of calculation and shape design for shafts, sliding bearings, thread couples, springs and other important components of machine.
