Automatic transmission(A/T) is one of a car’s core components. The durability of A/T has an effect on the durability of the car. The input shaft of A/T passes the power directly from the engine, so the durability of the input shaft for A/T is likewise vital. In this study, the test method of the input shaft is considered and the load spectrum of A/T is analyzed to secure durability of the input shaft. The shape parameter, T-N curve of the input shaft torsional fatigue test are obtained for life evaluation and analysis. Results of this study can be used to get the basic background of the durability test for A/T components.

Automatic transmission (A/T) is one of the most important of the core components for powertrain of car. The durability of A/T has an effect on the durability of car and Input shaft of A/T passed the power directly from the engine. So the durability of Input shaft for A/T is required. For Securing Durability of Input shaft, the test method of Input shaft is considered and the test results are analyzed. As a result of this study, the reliability of A/T reliability will be improved.

This study is performed by method for the influx of natural light in underground space. to solve the several negative underground issues make the covered courtyard and high reflected wall toward the adjacent space. for illuminance level test of sunken garden space, the adjacent space size is 15M × 9M × 12M sunken Garden with space to install the ceiling on the size of the companion light performance analysis, and seasonal changes derived by the light of changes in performance. In addition, increase the distance of the wall and the adjacent space and estimate the average at true time P.M12. The resulting data indicate that the road was an average lux DESKTOP RADIANCE of the modeling and analysis was conducted.
