จักรยานออกกำลังกายผลิตไฟแบบ ON-GRID
This Project presents electric bicycle. The structural feature is the use of the bicycle to be modified as it is designed to spin the rotor of the 5-phase magnetic line generator set and test the voltage distribution. The principle of operation of electric bicycles relies on the mechanical energy gained from cycling. The rotor consists of a series of permanent magnetic poles intersecting with a stator consisting of a set of conductor coils generating an AC voltage and converting it from AC to DC through a diode bridge to obtain DC voltage. To be connected to the boost converter to increase the output side pressure level to get the right voltage to charge a 12 volt battery. batteries. The test has been tested for cycling to generate electricity at a speed of 400 rpm while no-load has a voltage of 23.3 volt and with a load per load and at a speed of 400 rpm the voltage is 12.1 volt If the bicycle is cycled at an increased speed the voltage and current will increase. In order to transmit electric power to the single-phase power system an inverter is used to connect the single-phase power system to transmit to the single-phase power grid.
จักรยานพลังงานไฟฟ้าที่ติดตั้งแผง Solar Cell
This project presents an electric bicycle equipped with Solar Cell which will charge the battery with a solar panel. To be used to drive electric bicycles electric bicycles can be powered by two systems that are powered by the users cycling and from brushed DC motors from battery charging with solar panels the test will be tested by charging the panel with a time interval that the output voltage value From the solar panel which time interval is closer to the actual panel at 24 volts and charged into the batteryto test whether the electric bike can actually be used by a test drive starting with a displacement speed of 10 and 20 km/h at a distance of 100 meters. Using experiments with weight sizes of 50 60 and 70 kg respectively it was found that electric bicycles can actually be used. However the above project has been made into two parts. is the part that charges the battery from the solar panel and the second part is a separate electric bicycle.

This study Motorcycle Tourism Behavior: A Case Study of Motorcyclists in Bangkok aims to study personal factors of motorcyclists in tourism. Study the factors of motorcycling used in touring. And to study motorcycle tourism behavior of motorcycle users residing in Bangkok. The research employed a quantitative research. The research sample was 400 Motorcyclists in tourism residing in Bangkok. The research instrument was a questionnaire with five-level Likert scale. The data is described by frequency percentage and standard deviation. Most participants were male 20-29 years old had obtained a bachelor degree company employee monthly income in the range of 10001-20000 baht experience of driving motorcycling for tourism 5 years or more Used TOURING MOTORCYCLE engine size of 301 cc - 400 cc. and Use the Honda brand. The study results of tourism behavior factors. Tourists travel for a vacation during the months of November to December one day trip travel as a group or a caravan spend not more than 1000 baht per trip. travel in the west of Thailand and driving speeds between 51 - 100 km / h. Suggestions on Motorcycle Tourism Behavior. Study on the prevention of accidents from motorcycle tourism. This is because a motorcycle is a vehicle that can cause high damage in an accident.

This research is Study and design The Tourist Service Center and Rest the bikes and bike lane to develop Thai –Yuan culture tourist . Case study of culture Street. Ampor Sawhai. Province Saraburi. Study of the potential of case area to enhancing the area for tourism development of the area to increase even more. And design a tourist service center building. Rest the bikes path and Lane Bikes Breakpoint. To accommodate and service the ecotourism and Tai-Yuan culture in the area Study and design The tourist service center and rest the bikes and bike lane to develop Thai–Yuan culture tourist. Case study of culture street. Ampor Sawhai. Province Saraburi. Field data collection from down to the area. Using tools such as interview questionnaires in the interview area.Conclusion Building design Tourist center Bicycle break The researcher drew the pattern. The uniqueness of the Tai-Yuan architecture. Applied in the design. To be suitable and the shape of the modern era. Structures and materials are easy to construct and consisten t with the use of functional areas of buildings. access the building and the activity area. By landscaping that creates a shade with space. In the field of product design furniture field tested furniture before production. To test the strength which is at the level that passed the test criteria. The map design. Design has pulled the pattern. The uniqueness of the elements of Tai-Yuan is applied in the design in accordance with the building. In the design of bike lane layout. By designing the bike trails along the Tai-Yuan cultural lane line there are major breakpoints such as the intersection the floating market and the old community in the area. Presentation by analysis with aerial maps and identifying key points. For a design that covers the entire reachable area. The bike lanes offer a conceptual design that emphasizes safety and comfort and creates a good atmosphere for cycling.
การออกแบบและพัฒนาหุ่นทดสอบการชนรถจักรยานยนต์
The purpose of this research is to design and develop dummy (anthropometric test dummy) for motorcycle frontal collision test. The conceptual design of dummy is male aging between 25-55 years old 6 pieces of rib and deformable 76.2 mm. In order to performance test it was classified into 2 testing by static testing and dynamic testing. For static testing the energy absorption behavior between force and deflection or “ static curves” is determined. While dynamic testing is considered to the energy absorption behavior between forces and several velocities or dynamic forcedeformation curves impact acceleration impact force on sternum and injury severity with the relationship of viscous in velocity function. The results of the energy absorption behavior on chest of dummy from static testing the tendency of chest deflection is relatively low during the initial force and suddenly increasing when rise to the critical point. This behavior is similar to the energy absorption of the human chest. Therefore the design features of this test dummy can reflect behavior that is close to the human anatomy. In case of dynamic testing it is discovered the ability of the dummy testing to absorb up to 560 J impact acceleration 3 8 . 4 3 g impact force on sternum 5 . 0 9 4 kN. The viscous in velocity function is 0 . 8 2 5 m/ s which compared to injury severity at AIS3+ ( or higher than serious injury) . Therefore the dummy design in this research project corresponds to the collision test of a motorcycle.
