  • Development of next-generation vibration-fatigue software and Catia integration for the automotive industry [Elektronski vir]
    Slavič, Janko, 1978- ...
    This research describes the development of next-generation vibration-fatigue software for use in the automotive industry. Due to excitations caused by the engine and the road, many of the parts and ... assemblies built into a car are exposed to high-cycle fatigue loads, primarily in the form of sweepsine (e.g.,engine-born) and broad-band (e.g., road-born) excitations. If the excitation vibrations excite the natural modes of the cars structures, then they can significantly accelerate the vibration fatigue. Before the OEMs approve the final design, the critical parts and assemblies are required to withstand an experimental accelerated-vibration test. However, at the time of these accelerated vibration tests any design and manufacturing-process changesare very difficult to implement as well as being costly. Therefore, in order to help the designer in the early stages of the design process, a design-tool for vibration fatigue is required. The basics of vibration fatigue for the automotive industry are presented and typical sweep-sine and broad-band examples are given. The basic principles of vibration-fatigue calculations for typical broad-band and sweep-sine excitations are presented. A case-study is used to present the integration of the next-generation vibration-fatigue software into the automotive-industry-leading software, i.e., Catia
