This study was conducted to develop a system for detecting<br/> initial crack of an axle housing during durability test in the<br/> Lab.<br/> The system consists of air pressure sensor. wire sensor,<br/> <br/> I/O interface. and a computer. When the crack detection system developed in this study was used. the average length of crack was 5.6㎜ and the standard deviation of crack length was 1.5㎜. Comparing with the visual crack detection procedure, the average of crack length was decreased by 91.0% and the standard deviation of crack length was reduced by 94.7%.<br/>
