In the process of reconstruction of traffic accident, it is very necessary to have a analysis of human body's biomechanics simulation. Starting from the traffic case, the injury caused by the airbag to the human head is discovered. Establish the finite element model of airbag and use the human head model established by team to have a simulation and analyze. The simulation results are basically consistent...
This paper discusses a case study evaluating the potential impact of ITS traffic management on CO2 and Black carbon tailpipe emissions. Results are based on extensive microsimulations performed using a calibrated VISSIM model in combination with the AIRE model for calculating the tailpipe emissions from simulated vehicle trajectories. The ITS traffic management options hereby consist of easily implementable...
Transportation hub networks are important for many large-scale logistics and supply chain systems. Basic hub location models rely on some key assumptions about the transportation cost that limits their practicality We present a new model for hub location and network design that uses fixed and variable transportation costs on all arcs, fixed costs for hubs, and also allows direct arcs. This approach...
Emissions from represent a major component of airborne pollution. Transportation emission models are part of the modeling process of transportation planning. It introduces an important tool for the environmental evaluation of different transportation scenarios. Worldwide, there are several emission models. These models are categories to static and dynamic models. It depends on the amount of available...
Biodynamic feedthrough (BDFT) occurs when vehicle accelerations feed through the human body and cause involuntary control inputs. This paper proposes a model to quantitatively predict this effect in rotorcraft. This mathematical BDFT model aims to fill the gap between the currently existing black box BDFT models and physical BDFT models. The model structure was systematically constructed using asymptote...
Vehicle which is provided with power split Continuously Variable Transmission (CVT) drive system has been taken as entire car model in this paper, kinetics modeling and simulation analysis of the vehicle has been made progress. Dynamic response of the vehicle has been analyzed based on the wheel rolling resistance, air friction and grade resistance had been considered as total resistance of car driving...
For improving the intersection traffic capacity and reducing the vehicle emission, the solution that aim at the multi-object optimization was presented by using genetic algorithm (GA), and urban traffic microscopic simulation model (UTMSM) combined with GA was developed. The simulation was performed and the result indicated that the optimization method in this paper was effective to get better traffic...
Lots of researches were focus on aerodynamic characters of the head, top and tail of vehicle in the past, but researches on bottom of vehicle were quite rare. This has been changed in these days. Optimization of aerodynamics via shape of vehicle was limited by modern automotive styling. So the focus has been moved to bottom of vehicle. In current work, the aerodynamic influence of ground clearance...
In recent years, integrated vehicle control system has been designed based on the information of torque. Therefore, engine is teated as the actuator generating torque and necessity of controlling engine torque has been increased. This paper describes adaptive torque demand control of SI (Spark Ignition) engine with continuous variable valve lift which is based on STC (Self Tuning Control).
In allusion to underactuate and periodic of insect-like flapping wing micro air vehicle (FMAV), a method of the controller for FMAV is presented using averaging theory and time-periodic feedback. This method first approximates the non-steady dynamics of FMAV with its averaged system based on averaging theory. Then designs the time-periodic feedback controller by adjusts the wing kinematics parameters...
