초록

In this study, we suggested a design modification method to reduce the vibration of an air conditioner for railway vehicles and increase the durability of its pipe lines. Through experimental vibrational mode analyses and structural modifications on the air conditioning system, vibration reduction scheme was suggested and evaluated its effectiveness by empirical modal analysis. The derived design idea was applied to a real air conditioning system and the expected improvement was obtained.
