On-Site Test Data Analysis Helps Get Optimized Exhaust Flex-Joints to Market Faster and Reduce Design Risk
BOA specializes in the engineering and production of flex-joints for exhaust emission systems that decouple the engine motion from the exhaust structure. Exhaust flex-joints need to be custom engineered for each application in order to balance their static offset and dynamic motion, and ensure they meet fatigue life requirements for any automotive, commercial vehicle and off-road application. The data required for this custom design process is captured during road load data acquisition (RLDA) at a proving ground. In the past, several steps were required to analyze the data and it was necessary to manage every single step of this complex process using different software products which slowed the decision-making process.
BOA has streamlined its engineering process by implementing nCode GlyphWorks. GlyphWorks automates most of the test data analysis process and eliminates the need to convert file formats, thereby reducing the possibility of having to redo the analysis due to input errors. With some of the data analysis now completed on-site soon after RLDA, preliminary engineering decisions can be made on the spot and the RLDA can be concluded with confidence that additional data will not need to be collected later.
BOA Group is a leading system developer and supplier of flexible element technology, bellows, hoses and decoupling devices worldwide. Its customers include almost all European and North American, and many Asian manufacturers of passenger cars and commercial vehicles. BOA pioneered the multi-ply bellows design which absorbs thermal expansion and vibration in engine and compressor piping systems. The multi-ply bellows is manufactured from a laminated tube that consists of thin gauge stainless steel plies. This tubular body is formed into corrugations by a hydroforming process that delivers close tolerances. The use of thin gauge material combined with a large number of corrugations per unit length reduces deflection forces acting on and increases the flexibility of the bellows.
