Surface texture is one of the most important topics in today"s world of design, development and performance. As tolerances are shrinking and performance demands are increasing, surface texture is rapidly becoming one of the most important aspects of engine and vehicle performance. Every moving component on a vehicle or engine is influenced by surface texture in one or more of the following ways: vibration, sealing, adhesion, traction, emissions, safety, durability, wear/failure analysis. Many of the industry"s top warranty issues (leaks, noise, vibration, etc.) are a direct result of surface texture implications.
It’s estimated that over 40% of the on-board components in the entire car are electronic based and that percentage is expected to rise with the growth of hybrid and autonomous vehicles and will continue to be an enabling technology for a wide range of future loads with new features and functions. From lighting, infotainment, and safety systems, to powertrain systems and beyond, power electronics has become one of the most important areas of the automotive subsystem and bringing this technology to non-electrical engineers will help bridge a knowledge gap that will drive teams forward quicker and more efficiently.
Rubber – a loosely cross-linked network of polymer chains that when strained to high levels will forcibly return to at or near it original dimensions. This course is designed to provide the participant with a thorough understanding of rubber’s engineering characteristics. This class will introduce the various sources of rubber, both natural and synthetic. The class will contrast the differences between rubber and plastics; including thermoplastic rubber. Detailed discussions on how to select the correct rubber polymer for the application, highlighting the pros and cons of each major rubber type.
Silicone rubber is comprised of inorganic-organic polymers. These materials consist of an inorganic backbone with organic side groups attached to silicon atoms. This family of polymers possesses unmatched versatility giving the formulator and user multiple forms and methods to cross link the polymers into rubber materials having the widest service temperature range of any rubber material. This course is designed to provide the participant with a thorough understanding of silicone’s engineering characteristics.
Materials degradation from environmental conditions is a common factor that will often occur in mechanical equipment used in every type of environment. These processes can frequently materialize in unpredicted and harmful ways, especially when they interact and lead to early component damage or failure. This five-session course will summarize the mechanisms that cause materials and mechanical components to degrade in service through exposure to deleterious mechanical and environmental conditions.
Advanced High Strength Steels (AHSS) are now commonly used in automotive body structural applications. The high strength of this grade classification is attractive to help reduce mass in the automotive body through reduction in thickness. Strength also supports improvements in safety requirements so that mass increases are minimized. In some specific grades of AHSS, energy absorption is possible in addition to the high strength. This course will review the definition and properties of AHSS and cover several common applications in automotive body structures.
The relevance of innovative and functional lightweight components for aircrafts has risen significantly during the recent years. In this context, modern lightweight materials as well as cost-efficient and time-saving manufacturing technologies are required for a future aircraft production. The so called Hybrid SMC Technology and the SMC-Foam-Sandwich Technology are promising approaches for the cost-efficient and time-saving manufacturing of lightweight, geometrically complex and functional aircraft components. Both technologies have been used for the development of a new generation overhead stowage system. It is realized by sidewalls made out of enhanced SMC technologies with directly implemented metallic load introduction elements and regular sandwich structures that can be assembled by a quick-assembly principle.
Orbital drilling has proved to be advantageous to achieve aeronautical-level quality drilling (surface roughness, geometry control…) fully adapted for complex assemblies in a single operation. However, compared to conventional drilling method, this process leads to a drastic change in structure's fatigue life probably due to a non-optimised level of residual stress. The control of the mechanical behaviour of parts obtained by orbital drilling is the goal of the European-CleanSky collaborative R&D project RODEO (Robotized Orbital Drilling Equipment and Optimized Residual Stresses, GA no.738219). In this work, an orbital drilling unit (ORBIBOT) allowing high-speed-machining conditions was developed by PRECISE France, that can be integrated on a lightweight industrial robot. Cutting parameters were determined through an original Tool-Material Couple optimization strategy dedicated to orbital drilling, developed with MITIS Engineering and carried out on aluminium alloy 2024-T351.
