Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as an alternative choice of testing. Regarding to the problems as addressed above this project was aimed to design and test crash boxes which come in various structures; simple type corrugated type and honeycomb type of crash box. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. Numeric simulation and static test methodology of front collision were applied for these tests in reference to USA NCAP standard for automobile collision test. Testing all types of crash boxes indicated that the corrugated type was able to absorb energy at 2.8% and 5.9% higher than honeycomb type and rectangular type respectively. This is capable to pickup stress and strain continually and effecting to more energy absorb than another type. Additionally this corrugated structure is feasible and suitable for crash box design in automotive manufacturing.

The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.

The objective of research was to study and analysis the Electric vehicle structure of Rajamangala University of Technology Phra Nakhon. The Electric vehicle designed to save energy protect environment and cognitive development of student by used the computer software help in the design Material selection Finite Element Analysis Appropriability of the Electric Vehicle Structure and di s p l a c e m e n t of the vehicle structure by using the computer program help in the calculation for the Finite Element Method including to the development of engineering skill. The research must to create the Electric vehicle prototype to suitable and the structure have lightweight and strong for the electric vehicle and focuses on energy efficiency and the material of structure used steel pipe. This research can use to other working structure and future vehicle in sustainable. The vehicle has two seats Capable of running speed to 0-80 km/h the weight at the vehicle structure not over 1 0 0 kg. And the material of structure used steel pipe. This researching can use to other working structure and future vehicle in the sustainable.

The objectives of this research are to develop the structure to create the knowledge of construction technology to test the properties to construction the prototype building and to transfer the technology of hemisphere pre-engineered building with easy assembly steel structure type. The load and resistance factor design (LRFD) method was used to design the structure by regarding the strength material type construction and deconstruction step and cost. From the design the prototype of hemisphere pre-engineered building (only the frame structure) was construction with 5 meters of diameter 3.5 meters of height 19.635 square meters of useful space 200000 Baht of material cost (10186 Baht per square meter for all materials) 27 hours or 3 days of construction period. According to the modular coordination system this hemisphere pre-engineered building cans construction and deconstruction fast especially when apply to help disaster victims. After tested the structure that the calculation value of safety factor (S.F.) is 1.76. The envelope of this building used the ratio of Portland cement type 1: fine sand: coconut fiber: waterproofed liquid: tap water which equal to 1:3: 0.1: 0.02: 0.5 by weight and reinforced by round bar and wire mesh steel. According to the testing the building-envelope properties are following: density 1582 kg/m3 thermal conductivity coefficient 0 .3 7 1 watt/m.Kelvin water absorption 1 7 .3 1 % compressive strength 118.47 ksc and bending strength 28.88 ksc. Moreover these results can register the copyright and draft the research paper to transfer the technology for target group.

Project design guys costume in case structure of Park Venture architecture The purpose was learned structure of Park Venture and design of guys costume. To adapt in commercial make it to be unique new and difference style for enhance personality and identity of customer. Project design for learning project structure of Park Venture architecture study in descriptive analyze. Using equipment and analyze condition in design after that divide criterion in 2 side. We found building structure has changed to new style from innovation of construction but better than old construction in many structure condition pattern of building. Building shape inspire from pay obeisance and slant pattern of building look like lotus until head of building to make pattern. Project design guys costume to get guys costume casual style sweater jacket and long pants. Bringing pattern of structure of Park Venture adapt to condition of costume use color after winter time to make it beautiful and difference and also able to wear in daily life. To answer need of customer and communicate clear personality
