Abstract Due to recent oil price crisis and an ever-increasing public awareness on environmental issues, an interest in electric vehicles (EV) has increased tremendously in Thailand and other Asian countries over the last few years. In this study, a prototype of 9-metre battery electric vehicle (BEV) bus was chosen as a vehicle of interest to undergo a series of field test by operating the lead acid battery powered electric bus in order to estimate a power demand of the bus as well as to evaluate a battery performance characteristic Two different types of battery were employed in this study i.e. a flooded-type deep cycle lead acid battery and a valve regulated lead acid (VRLA) battery. The effect of different driving modes available from the drive motor i.e. normal, max power, max range, as well as regenerative braking feature would be investigated while an influence of drivers were also taken into account to ensure the repeatability of the obtained results.

Abstract In this study, a prospect of employing electric fans in a battery cooling system was investigated by means of a computational fluid dynamic (CFD) analysis. The concept was to have the fans to stimulate appropriate air flows inside the battery compartment. A rear utility space behind back passenger seats was dedicated for the battery compartment containing 100 cells of Lithium Ion batteries. Due to limited working space, a battery arrangement was conceived as a double stacking configuration. In computational analysis, the heat source model of employed batteries was obtained from the experimental work. Several potential designs of cooling patterns were investigated. The design parameters of interest were locations of inlet/outlet, and air flow rate. The performance criteria of cooling system were resulting battery temperatures, temperature distribution uniformity, required pump pressure, and structural integrity.

Abstract In this study, the method of analyzing the thin-wall crashing box of impact attenuator for student formula is proposed by the means of simulation and validation following Formula Society of Automotive Engineers-SAE rules. The analysis was performed based on computerized simulation software for calculated the absorption capacity of the simple and multiple cell of thin-walled tubes. The effect of thin-wall thickness consisted of 1.2 mm, 1.6 mm and 2.0 mm was also evaluated. The simulation results as energy absorption, crashing force efficiency, and absorbed energy per unit mass were identified among nine patterns. According to the results, the increase of interior cell number and the wall thickness contribute the absorbed energy ability. However, the increment of wall thickness lead to the increase of crashing force magnitude. Regarding the kinetic energy, a 2×2 multiple cell box with the thickness of 2 mm is designated for construction and verify.

Abstract The road accident is major concern around the world, so do Thailand. It is caused by three main factors: man, vehicle and infrastructure. The most important part that accounts the safety of vehicle is human. With experiences and careful driver, the accident could be diminished. So that the vehicle monitoring systems are the vital tools to screen out the inexperience or aggressive driver. In this paper, we state the problem about the dangerous driving behavior by monitoring lateral and longitudinal acceleration. For this purpose, the inertial measurement unit should be applied but it is inconvenient to install in the vehicle. Consequently, the vehicle monitoring system were developed based on novel consumer grade multi-satellite navigation receivers and were compared to Racelogic Video V-Box system in controlled condition tested track. The incidents were virtually detected and reviewed. The incident detection algorithm were proposed and tested alongside with receivers.

Abstract The road accident is major problem around the world and also in Thailand, The main cause is concerning the driving behavior e.g. uncarefulness, aggression, drowsiness and etc. Dangerous driving is categorized by means of lateral vehicle dynamics when the turning or lane changing is performed, and longitudinal one if the braking or rapid acceleration is occurred. For this reason, we developed the vehicle monitoring system based on novel consumer grade multi-satellite navigation receivers and proposed the lateral acceleration estimation from these data. The system were tested within controlled condition tested track. The multiple satellite system, GPS and multi-GNSS: GPS+Glonass and GPS+Beidou were tested and compared to the reference inertial measurement unit (IMU) As results, the maximum lateral acceleration in tested track were chosen and compared with reference IMU.

The purpose of this SAE Aerospace Information Report (AIR) is to provide information that would be useful to potential users/operators and decision makers for evaluating and quantifying the benefits of an Engine Monitoring Systems (EMS) versus its cost of implementation. This document presents excerpts from reports developed to analyze "actual aircraft cost/benefits results". These are presented as follows: a. First, to outline the benefits and cost elements pertaining to EMS that may be used in performing a cost versus benefits analysis. b. Second, to present considerations for use in conducting the analysis. c. Third, to provide examples of analyses and results as they relate to the user/operator and decision-maker community. The document encompasses helicopters and fixed wing aircraft and distinguishes between civilian and military considerations.
