25. TRANSPORTING CHILDREN IN CARS AND THE USE OF CHILD SAFETY RESTRAINT SYSTEMS
ABSTRACT Objective: To evaluate the transport of children in automobiles and the use of child restraints systems (CRS). Methods: This is a transversal descriptive study which included 200 vehicle drivers who carried 0-10 year old children in the city of São Luis, MA, Brazil. The drivers' passengers' and children's features were properly identified. The ch

26. Experimental Development of Dual Phase Steel Laser-arc Hybrid Welding and its Comparison to Laser and Gas Metal Arc Welding
Abstract Dual phase DP600 steels have been used in many automobile structures and laser welding has been the standard method for the joining of different sections. This work proposed a comparison between laser welding with arc welding (GMAW) and with hybrid laser-arc welding in order to access the microstructures and the mechanical behavior. The laser and hy

27. Experimental Study of Tensile Test in Resistance Spot Welding Process
Abstract Resistance spot welding (RSW) is a widely used joining process for fabricating sheet metal assemblies in automobile industry .In comparison with other welding processes the RSW is faster and easier for automation. This process involves electrical, thermal and mechanical interactions. Resistance spot welding primarily takes place by localized melting

28. An experimental investigation of static load capacity of AL-GFRP adhesively bonded single lap and double butt lap joints
AbstractThis paper is focused on experimental evaluation and comparison of progressive damage behaviors in adhesively bonded single lap and double butt lap joints between aluminum and glass fiber reinforced plastic (GFRP). The effect of joint design and dissimilarity of adherents on damage evolution of adhesive bonding under tensile quasi static loading is a

29. Multi objective optimization of foam-filled circular tubes for quasi-static and dynamic responses
AbstractFuel consumption and safety are currently key aspects in automobile design. The foam-filled thin-walled aluminium tube represents a potentially effective material for use in the automotive industry, due to its energy absorption capability and light weight. Multi-objective crashworthiness design optimization for foam-filled double cylindrical tubes is

31. Velocidad de corrosión de una aleación base plomo en una solución de ácido sulfúrico a diferentes temperaturas
Car batteries are not only affected by their use and wear but also by other factors such as electrolyte concentration, water loss and temperature that can be exposed, the latter being the most influential factor causing an increase in the corrosion rate of lead alloys (battery components), and affecting their service time. Therefore, for the industry of auto

32. A Multi-objective, active fuzzy force controller in control of flexible wiper system
Chaotic vibration has been identified in the flexible automotive wiper blade at certain wiping speeds. This irregular vibration not only decreases the wiping efficiency, but also degrades the driving comfort. A reliable nonlinear system identification namely nonlinear auto regressive exogenous Elman neural network (NARXENN) was adopted in first stage of this

34. Study of mechanical properties and durability of magnesium phosphate cement matrix containing grinding dust
The acid-base cements are materials developed by means of reactions between an acid component and another basic one. This type cement belongs to the family of the so called "chemically bonded phosphate ceramics" (CBPCs), new types of inorganic materials that have special physico-chemical properties and that, in contrast to most advanced ceramics, are made by

35. Weibull analysis for the diameter dependence of the elastic modulus of curaua fibers
The curaua fiber is one of the strongest lignocellulosic fibers and is currently being considered as reinforcement of polymer composites for industrial applications such as automobile interior components and bicycle helmets. The tensile strength of the curaua fiber was found to display an inverse variation with its corresponding equivalent diameter. Since th
