In this study, the optimization of robotic gas metal arc welding (GMAW) parameters for joining hot-rolled ferritic-bainitic FB590 steel sheets with a thickness of 2.5 mm was investigated. The main objective was to evaluate the effect of wire feed speed and welding speed on the penetration depth, throat thickness, and mechanical performance of the welded joint. A series of welding experiments were carried out with wire feed speeds ranging from 50 cm/min to 100 cm/min and welding speeds ranging from 5 cm/min to 15 cm/min. Tensile and microhardness tests were carried out to evaluate the structural integrity of the welded joints. The results show that increasing the wire feed speed significantly improves the weld penetration and throat thickness, especially at constant welding speeds. The most suitable combination was found to be 70 cm/min wire feed at 8 cm/min travel speed and 100 cm/min wire feed at 12 cm/min and 15 cm/min travel speeds. The microhardness in the heat-affected zone

Measurement plays a crucial role in the precise and accurate management of automotive subsystems to enhance efficiency and performance. Sensors are essential for achieving high levels of accuracy and precision in control applications. Rapid technical advancements have transformed the automobile industry in recent years, and a wide range of novel sensor devices are being released to the market to speed up the development of autonomous vehicle technology. Nonetheless, stricter regulations for reliable pressure sensors in automobiles have resulted from growing legal pressures from regulatory bodies. This work proposes and investigates a tribo electric nano sensor that is affected by a changing parameter of the separation distance between the device's primary electrode and dielectric layers. The system is being modeled using the COMSOL multiphysics of electrostatics and the tribo-electric effect. Open circuit electric potential and short circuit surface charge density are two of the

Like those in many other industries, truck and off-highway vehicle manufacturers face the challenge of producing quality components and maintaining productive processes while also generating a better bottom line. Improving employee training, simplifying complex operations and implementing better workflows can all help generate efficiencies. While not a new concept, lightweighting - in this case, reducing the weight of parts through the substitution of traditional steel with high-strength, thinner steels - can also be a viable answer to a better vehicle. As a rule of thumb, when manufacturers double the strength of the material through lightweighting, it is possible to reduce the weight of the part by one-third. That weight reduction can then lower the cost per part for greater profitability per piece of equipment and greater annual savings.

Additive Manufacturing is currently being utilized to improve military readiness by transforming maintenance operations and the supply chain associated with repairing or replacing parts or components on legacy vehicles. The National Institute for Aviation Research at Wichita State University is collaborating with the Army Ground Vehicle Systems Center in the creation of a rapid qualification framework for various additive manufacturing materials and processes to support the modernization and sustainment of ground vehicles. Currently, a rapid qualification 17-4PH stainless steel material is being executed utilizing Laser Powder Bed Fusion and Direct Energy Deposition additive manufacturing processes. Prior to entering the rapid qualification, pre-qualification screening studies are performed to select the feedstock and develop process control to limit risk within the qualification. An overview of the pre-qualification screening studies performed in selecting the feedstock and heat

Advanced ferritic nitrocarburizing process combined with a specialized post-oxidation treatment described as FNC + Smart ONC® [1] is developed for brake rotor applications. The process can be applied to standard grey cast iron brake rotors, significantly reducing PM 10 emissions to levels below the Euro 7 limits for most vehicles equipped with at least some recuperative braking capabilities, all without compromising performance. Finished grey iron brake rotors, ferritic nitrocarburized and post oxidized were evaluated according to several industry standards. The standards include SAE J2707B (Block Wear Test including Highway) [2], GRPE-90-24 Rev.1 Emission Test (Full WLTP Brake Cycle 6 Times) [3], and SAE J2522 (AK-Master Performance) [4]. Nitrocarburized post oxidized brake rotors were compared to untreated grey iron rotors exposed to several friction materials. Ferritic nitrocarburizing and post oxidation addresses the issue of corrosion, which is particularly relevant for brake

The rapid development of electric mobility leads to improve the performance of all the powertrain components. There is still a high need to maximize their efficiency for autonomy reasons, but weight and volume are critical parameters for automotive, aeronautic or train applications. This paper focuses on electrical machines, especially the permanent magnet synchronous axial flux motors (PMSAFM) which offer advantages in terms of power density and volumetric electromagnetic torque. The paper proposes a panorama of solutions for designing such a motor, with an application case to 100 kW – 10000 rpm, and an objective of 12 kW/kg at steady state. Obtaining such a power density can be obtained by optimizing the design, by boosting the current, using a high DC voltage, choosing a high-performance electrical steel and adapted permanent magnets, etc). For the PMSAFM topologies several configurations can be considered, and the authors show that a double rotor PMSAFM surface-mounted magnets

Compressive residual stresses are very important at fatigue life, therefore this work has an objective to determine compressive residual stresses longitudinally, along a surface, with three levels of deflection causing tensile prestresses on the surface fibers, of 750 MPa, 1100 MPa and 1500 MPa, supported in one support position on the compression side, 150 mm, equidistant from the longitudinal center of the samples, which are made of EN 47 steel (DIN 51CrV4), with dimensions of 15 mm thick, 70 mm width and 1500 mm long. The samples are submitted to quenching, tempering, surface polishing and stress relief processes, with radius of 2500 mm and concavity downwards, and after they are immersed in a tank with mineral and conventional quenching oil compound, then the samples are tempered and the concave surfaces are polished to remove decarburization and took into the furnace to relieve stress caused by the surface polishing process. Next step, the samples are peened, with deflections of

The continuous improvement of validation methodologies for mobility industry components is essential to ensure vehicle quality, safety, and performance. In the context of mechanical suspensions, leaf springs play a crucial role in vehicle dynamics, comfort, and durability. Material validation is based on steel production data, complemented by laboratory analyses such as tensile testing, hardness measurements, metallography, and residual stress analysis, ensuring that mechanical properties meet fatigue resistance requirements and expected durability. For performance evaluation, fatigue tests are conducted under vertical loads, with the possibility of including "windup" simulations when necessary. To enhance correlation accuracy, original suspension components are used during testing, allowing for a more precise validation of the entire system. Additionally, dynamic stiffness measurements provide valuable input for vehicle dynamics and suspension geometry analysis software, aiding in

A Rear Underrun Protection Device (RUPD) is a safety feature installed on the rear end of chassis of trailers, designed to prevent smaller vehicles from sliding underneath the rear of the trailer in the event of a collision. Therefore, it plays a critical role in reducing the risk of serious injuries or fatalities. The RUPD standard is updated aiming to improve the strength and resistance of these devices, therefore improving the road safety. This paper shares the author’s experience with the latest standards and regulations for Rear Underrun Protection Devices (RUPD), with a focus on the use of Advanced High Strength Steel (AHSS). It provides a general overview of RUPD standard requirements and suggests several AHSS steel tube sizes suitable for the main longitudinal member, serving as a starting point for design. Key design parameters and potential failure points in RUPD structures are discussed, along with possible solutions. Finite Element Modeling (FEM) is commonly used in the
