  • Generally, automobile cooling fan is used to lower the temperature of radiator. The cooling fans are manufactured by plastic injection molding process. The center of gravity of cooling fan is often deviated from the center because of the use of deteriorated materials. As the unbalance of the cooing fan can generate noise, it is required to test the performance of the cooling fans. In this work, automatic fan balancer which can distinguish between the good and the bad, futhermore idenfify the position and magnitude of unbalance is develpoed.

  • This study aims to develop the plastic suspension assembly which is installed on inside of vehicle seat and supports passenger's back to provide the comfortable feeling. This design is the suspension structure to support the back equally and assemble seat back frame and plastic suspension effectively. The parts of suspension are designed by considering the property of body pressure distribution. As analysis values are approached to measured values by comparing the deformations in the cases of existed spring suspension and developed plastic suspension, the optimum design can be established.

  • Generally, automobile cooling fan is used to lower the temperature of radiator. The cooling fans are manufactured by plastic injection molding process. The center of gravity of cooling fan is often deviated from the center due to the use of deteriorated materials. As the unbalanced of the cooing fan can generate noise, it is required to measure the degree of deviation of center of gravity in the cooling fan. In this work, automatic fan balancer which can effectively detect the magnitude and position of the unbalanced cooling fan is proposed and several experiments are carried out to verify the feasibility of the proposed algorithm.

  • Recently the requirements for light weight and high performance of the automobile have increased. Especially, the plastic fuel tube makers have made their efforts to dove]op the various plastic fuel tube module with not only dimensional accuracy but also cost competitiveness. The experiment is performed to investigate spring backs for PA12 plastic fuel tubes in case of compound bending. In the experiment, steam bending process is adopted as bending method. In this study, the results we obtained are used to design the bending fixtures and the compound bending system.

  • Recently the plastic fuel tube is usually used to reduce production cost and weight in automobiles. These days, material used to plastic fuel tube is the polyamide12. The fuel tube is made of the PA12. Post deformation of the tube has been changed by environmental temperature. So, it is important to prevent post deformation. The experiment is performed to investigate post deformation of the tube produced by each bending process. In this study, the results we obtained are used to bending process system for post deformation as the environmental temperature of the tube. It turned out that the method of steam heating and air cooling was shown less deformation than other methods.
