Parametric design optimization of an automotive body crashworthiness improvement is presented. The thicknesses of parts are employed as design variables for optimization whose objective is to increase the maximum deceleration value of the vehicle center of gravity during an impact. Using the Taguchi method, this study analyzes the optimum conditions for design objectives and the impact factors ...
the semi-classical model of atom-field interaction has been fully studied for some multilevel atoms, e.g. vee, l, cascade x , y, and inverted y and so on. this issue is developed into the full-quantum electrodynamics formalism, where the probe and coupling electromagnetic fields are quantized. in this article, we investigate the full-quantum model of absorption and dispersion spectrum of trappe...
projects: Software Enabled Control (SEC), SEC Renegade (a follow-on to the SEC project funded to apply SEC technologies to a full-scale rotorcraft), and Heterogeneous Urban Reconnaissance, Surveillance, and Target Acquisition Team (HURT). My deepest thanks are for Professor George J. Vachtsevanos, who advised me through the completion of this work. His critical input, guidance, and mentoring ha...
In recent years there has been an increased effort to investigate and improve the crashworthiness of passenger rail vehicles in the United States. The structural crashworthiness requirements for new rail vehicles are changing to include specifications for crash energy management and crush zones rather than primarily specifications of vehicle and component strengths. In addition, the structural ...
Evacuations requiring large numbers of pedestrians to evacuate and potentially interact with vehicles are unique in the complexity of interactions that must be understood and in the potentially catastrophic consequences of poor management. On the pedestrian side alone, these events, which may result from a variety of causes including terrorist attacks, bomb threats, and building fires, require ...
Series of experiments on material recognition were carried out on a full-scale prototype of customs inspection system for vehicles and large-scale containers developed by Efremov Research Institute. The 8 MeV linear electron accelerator operating in 4-8 MeV range dual energy mode was used as an X-ray source. Experimental interlaced images of tested samples and real cargo container were processe...
The focus of this paper is on a large-scale reliability based design optimization of a car body structure for crash safety. The application of multidisciplinary design optimization (MDO) to automotive vehicle structure design has been an interest topic over the past several years (Yang et al. 1994, Schramm et al. 1999). Sobieski et al. (2000) and Kodiyalam et al. (2001) reported a method with v...
In this paper, the 1/4 vehicle model have been simulated. The vehicle body acceleration using optimal control has been optimized. The vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. The active suspension can help the vehicle to have a good dynamic behavioral. In this paper, two degrees of freedom dynamic vibration model of a general ve...
