In the research process, a nonlinear three-degrees-of-freedom vehicle model has been developed. By utilizing a zero-moment point index as a rollover warning indicator, this approach could accurately detect the rollover status of the vehicle, particularly in scenarios involving low road adhesion on unpaved surfaces, which are characteristic of ATV operation. The differential braking, generating a roll moment by adjusting the amount of lateral force each braked tire can generate, was proved as an effective method to enhance rolling stability. Simulation and on-road testing results indicated that this control strategy effectively monitored the state of the ATV and Hong, Hanchi, Wang, Kuan, d’Apolito, Luigi, Quan, Kangning, Yao, Xu Anti-Rollover Control for All-Terrain Vehicle Based on Zero-Moment Point 2024-01-5055 create equalizer 04/30/2024 Technical Paper more_vert lock SAE BRIEFS: The Future of Hydrogen-Powered Class 8 Vehicles 13451 04/30/2024 With all the hype around battery EVs, what role will hydrogen propulsion play in the future of sustainable transportation?

However, current λ sensors suffer from long light-off times (on the order of seconds following a cold start) and limited time resolution. In this study, a four-color mid-infrared laser absorption spectroscopy (LAS) sensor was developed to provide 5 kHz measurements of temperature, CO, CO2, and NO in engine-out exhaust. This LAS sensor was then combined with 1 kHz hydrocarbon (HC) measurements from a flame ionization detector (FID), and the Spindt exhaust gas analysis method to provide 1 kHz measurements of λ. To the authors’ knowledge, this is the first time-resolved measurement of λ during engine cold starts using the full Spindt method. Three tests with various engine AFR calibrations were conducted and analyzed: (1) 10% lean, (2) stoichiometric, and (3) 10% rich.

Why? Because increased automation doesn't eliminate humans, it allows them to focus on higher level tasks that make scaling air taxis safer and more accessible. That's the vision behind Wisk Aero, an urban air-mobility company on a mission to leave traffic on the ground and make sustainable, autonomous flight a reality for everyday life. The company is building and certifying the world's first autonomous eVTOL aircraft for commercial passenger use and working with the FAA on a type certification program. To learn more, we sat down with Brian Yutko, CEO, Wisk Aero, to discuss the company's critical interface between autonomy and human oversight, working with the FAA from a regulatory standpoint, the strategic advantages of the Wisk's aircraft design, and the future of autonomous eVTOL flight Hineman, Marcie Podcast more_vert lock The machining process is employed to transform a workpiece into a predefined geometry with the assistance of a cutting tool. Throughout this process, the cutting tool undergoes various adverse effects, including deformation, stress, thermal gradient, and more, all of which impact tool sharpness, surface finish, and tool life. These outcomes are also influenced by cutting parameters, specifically cutting speed, feed rate, and depth of cut. The present investigation aims to demonstrate the application of ANSYS analysis software in predicting stress, deformation, thermal gradient, and other factors on the tool insert tip for various machining parameters. To achieve this, an experimental setup was arranged to collect cutting force and temperature data using a dynamometer and thermocouples during the machining process of maraging steel with a tungsten carbide tool insert. Experiments were conducted with different combinations of machining parameters using design of experiments (DoE).

In the automobile industry, addressing vehicular emissions is crucial due to environmental ramifications and stringent regulatory mandates. This study presents an innovative and potentially cost-effective solution to capture CO emissions, mainly from motorcycles. The eco-friendly nature of using rice husks and the detailed findings on optimal conditions (20 m/s gas flow rate, 0.47 M citric acid concentration, and 30 g mass of activated carbon) make this research invaluable. These conditions achieved a commendable CO adsorption rate of 54.96 ppm over 1250 s. Essentially, the insights from this research could spearhead the development of sustainable automobile exhaust systems. By integrating activated carbon into these systems, there’s potential to capture CO and possibly other detrimental gases, reducing the Natrayan, L., Seeniappan, Kaliappan Optimizing Carbon Monoxide Emission Reduction Using Rice Husk Activated Carbon in Automobile Exhaust Systems 2024-01-5054 create equalizer 04/29/2024 Technical Paper more_vert lock The present study focuses on the impacts of pistachio shell particles (2–10 wt.%) on the mechanical and microstructures properties of Al–Cu–Mg/pistachio shell particulate composites. To inspect the impact of the pistachio shell powder content with Al–Cu–Mg alloys, the experimentation was carried out with different alloy samples with constant copper (Cu) and magnesium (Mg) content. Parameters such as hardness, tensile strength with yield strength and % elongation, impact energy, and microstructure were analyzed. The outcomes demonstrated that the uniform dissemination of the pistachio shell particles with the microstructure of Al–Cu–Mg/pistachio shell composite particulates is the central point liable for the enhancement of the mechanical properties. Incorporating pistachio shell particles, up to 10 wt.%, is a cost-effective reinforcement in the production of metal matrix composites for various manufacturing applications Om Prakash, S., Srinivasan, V., Selvaraj, Dinesh Kirupha, Nandhakumar, S., Dharmaraj, T.B.

The connection is formed between a stack of three AA6016-T4 aluminum sheets and one SPR. The calibration process involves material characterization, a detailed riveting process simulation, virtual joint unit tests, and the final large-scale model calibration. The virtual tests were simulated by detailed solid element FE models of the joint unit. These detailed models were validated using experimental tests, namely peeling, single-lap joint, and cross-tests. The virtual parameter calibration was compared to the experimental calibration and finally applied to component test simulations.

For use in automobile flooring trays and underbody shields, this study examines the impact of injection molding on composite materials made of polyvinyl chloride (PVC) and Linum usitatissimum (flax) fibers. As processed organic fiber content was increased, the bending and tensile rigidity initially witnessed an upsurge, peaking at a specific fiber loading. At this optimal loading, the composite exhibited tensile strength, flexural strength, and elastic modulus values of 41.26 MPa, 52.32 MPa, and 2.65 GPa, respectively. Given their deformation resistance and impact absorption attributes, the mechanical properties recorded suggest that such composites can be efficiently utilized for automotive underbody shields and floor trays.

Vehicle path-tracking control is an important link in achieving intelligent driving of vehicles. This paper designs a controller that combines path tracking with vehicle lateral stability for four-wheel steer/drive agricultural special electric vehicles. First, based on a simplified three-degrees-of-freedom vehicle dynamics model, a model predictive control (MPC) controller is used to calculate the front and rear axle angles. Then, according to the Ackermann steering principle, the four-wheel independent angles are calculated using the front and rear axle angles to achieve tracking of the target trajectory. For vehicle lateral stability, the sliding mode control (SMC) is used to calculate the required direct yaw moment control (DYC) of the vehicle, and wheel torque distribution Huang, Bin, Yang, Nuorong, Ma, Liutao, Wei, Lexia Path-Tracking Control for Four-Wheel Steer/Drive Agricultural Special Electric Vehicles Considering Stability 2024-01-5051 create equalizer 04/25/2024 Technical Paper more_vert lock This specification covers a titanium alloy in the form of bars, forgings, and flash-welded rings up through 12.000 inches (304.80 mm), inclusive, in diameter or least distance between parallel sides, and stock of any size for forging or flash-welded rings.
