Experiment and computer simulation for the adsorption energy of thin-walled tubes by using aluminum foam filled under torque.1. The background and significance of the problem.Development of structure and parts within the structure efficiency and high safety. Under the impact, such as barrier barrier at the edge of the curve bridge. Signs and bumper cars, etc., to make better of these structures. To reduce the risk of accidents. This would lead to injury and loss of life of the driver. So in the design, the impact of structure variables importance, including maximum force, the ability to absorb the energy of the structure. Specific energy absorption efficiency and maximum force, etc., the designer must พยายามเลือก use the size, shape, type of material, behavior, structural damage, according to the needs and conditions of the parameters in general. The structure of vehicles and structures along the road Design and development of the efficiency and the selection of proper parameters To enhance the ability to absorb the energy of the structure effectively.Study variables such important of thin-walled tubes cross-sectional shapes square cross-sectional shapes hexagon and cross-sectional shapes circle fill foam under torque. By studying the parameters such as the effect of cross-sectional shapes. The effects of the thickness of the pipe, and the density of the foam. With the changes in the ability to absorb the energy which the analysis result will be “ตัว absorbs energy "with the ability to absorb more energy. To be installed around the high impact strength. The injuries and deaths due to accidents to a minimum.2. Objective.1. To investigate the adsorption energy of the pipe is made of aluminum. Cross-sectional shapes square cross-sectional shapes hexagonal. And cross-sectional shapes circle do not fill the foam and foam filled under torque.2. To study an important variable, such as the effects of thickness, the effect of foam density effect of cross-sectional shapes, and the number of squares that.
