This research practically discusses and presents the stages of design process in product development. Design process was realized through CATIA. The product developed is an agricultural device called as “disc harrow”. Therefore, agricultural details are presented together with machine design. A roller system is added to disc harrow in this study. Thus; the current system and the additional roller system are discussed with the principles of methodological construction and design objectives are defined. Both the current system and the additional roller system are designed in parallel with these objectives. Structural stress analysis is performed at different kinetic positions of the disc harrow connection of the roller system. System design is achieved by considering the feedback from such analyses and design objectives. The hereby design is obtained. The additional roller system is mounted and field survey is carried out. Contribution of the roller to disc harrow process, defined design objectives, ratio of the realization of design objectives and results of stress analyses are evaluated.

In this study, an axle shaft subjected to static deformation and fatigue damage was considered by using computer-aided engineering. This shaft system was modeled with CATIA and subjected to dynamic fatigue analyses with Ansys workbench. The damaged fracture surfaces of the shaft have been examined. Thus, the fatigue and damage was revealed in greater detail. For the present system, a design with a minimum cost, short production process, minimum weight was sought together with methodical construction principles. By means of CATIA and ANSYS, the product development design with reasonable tension and deformation values was formed for endless life fatigue. A design was produced in a short space of time with the help of 2D CATIA drawings and field tests were carried out. The design was used through 560.000 cycles and damage was not observed.

Stress analysis obtained from CAE methods is one of the most important parameter of designing parts, assemblies and constructions. Loads and stress limits applied on the model should be known also for better design procedure. Evaluation of all parameters is known as optimization. Designed model should contain the optimum values of each parameters such as loads, stresses and weight. Designer creates the model using optimized values for better products. In this paper, Computer Aided Engineering Design Optimization process is studied experimentally with CATIA Product Engineering Optimizer module and optimization algorithms within limitations are used. Benefits of the optimization procedure is also evaluated. Optimization process and benefits are presented in an example of I profile cantilever beam with a length of 2000 mm.
