Mechanical strength test of train wheel based on virtual prototyping
Journal Title: Proceedings in Manufacturing Systems - Year 2015, Vol 10, Issue 3
Abstract
Virtual prototyping becomes more and more a less-expensive alternative of physical mockups. Its applicability to product certification procedures is already included in several standards where it is possible to replace completely physical prototyping and testing. A sample is given based on the standard for assessment of mechanical behavior of railway applications – wheel sets and bogies – EN 13979-1:2003+A1:2009. This study includes developed assessment approach for wheel mechanical strength check using engineering analyses, based on virtual prototyping technology. The approach contains 6 steps that allow user to determine required by the standard dynamic stress maximal values and to compare them against permissible ranges stated in the standard. Developed approach is demonstrated by an example of monoblock wheel for train vehicle up to 50t load capacity. This example shows an effective way to reduce expenses and obtain a cost-effective solution as well as to shorten time to reach market. Additional advantage is design evaluation at early stage of product life cycle and possibility to explore structural behavior in detail as to improve product performance. Virtual prototyping application combines overall product performance optimization, time and expenses reduction and detailed diagnosis of ongoing physical phenomena.
