Engineering – Global BOA standards – Local support
As a globally operating manufacturer with more than 100 years of experience, we know about the typical technical requirements of our clients. A team of highly skilled engineers and designers ensures local systematic engineering and planning support while applying harmonized global BOA engineering practices and tools.
Simplifying Complex Tasks Provides Opportunities for Innovation
The BOA Group has designed some of the most complex bellows products in the marketplace, with high-technology components on the International Space Station, on commercial and military aircraft, in emissions components for heavy trucks and passenger cars as well as in giant LNG vessels, Concentrated Solar Power stations or Fluid Catalytic Cracking oil refining processes.
Advanced Design and Analysis Tools
Part of an organization-wide commitment to systematic planning and execution, BOA has invested heavily in the up-front process necessary to analyze, monitor, and mitigate risk on all our programs, whether it is about:
- Small or large diameter application
- Hot or cold temperature conditions
- Static or dynamic load input
- High or very low required spring rate
- A specific unique product or standard high volume production
3-D solid modeling using Catia V4-V5, AutoCAD®, Pro/Engineer® and SOLID WORKS®, ensures exacting component design. While BOA designs the process with the product, BOA’s engineers and program managers work concurrently with the customer to design products while the customer designs a higher-level system or subsystem. Efficiency and minimized risks are the keys from the beginning to meet customer expectations.
State of the art FEA tools such as MSC Nastran®, MSC Marc®, MSC Fatigue® or ANSYS® simulate working loads on the bellows and connected sub components. Calculation models are regularly reviewed against test results and durability experience in the field for the highest reliability.
Modal analysis is used to manage vibration inputs and ensure durable product solutions while improving noise, vibration and comfort levels in passenger cabins.
The BOA Group is one of the pioneers introducing a mobile automotive measurement system in order to analyze the motion of flexible elements in exhaust systems while driving under most severe conditions on the test tracks of global automotive key accounts. Measurements include 12 DOF (degrees of freedom) of the engine and the flex element, 6 DOF of engine, 6 DOF of the flex element as well as the temperature of components.
Real measurement data can be simulated and durability tested on RMS (real motion simulator) test benches under working temperature and at 6 DOF.
Metallographic laboratories and additional equipment for measuring life cycle data, static and dynamic stiffness as well as corrosion influence complete the BOA service portfolio.
The BOA Engineering and Design facilities are audited as per ISO/TS 16949 and ISO 9001 every year. BOA is proud member of the American EJMA (Expansion Joint Manufacturers Association) as well as of the European Association Euroqualiflex fully respecting the highest industry standards.
