초록
An underwater cable guide device which is using the caterpillar movement to move smoothly along the slippery and curved surface of the cast iron pipe was developed. We performed structural analysis with maximum stress and structural safety for the designed guide device. As a result of the structural analysis, the maximum stress occurred between the connecting link and the pin, and it was confirmed that it was structurally safe by satisfying the safety factor of 2.5 or more. In addition, we performed modal analysis to find out the possibility of resonance between the guide device and motor for driving the Caterpillar. The natural frequency of guide device was calculated to be higher than the frequency of motor ,so no resonance was found. We tested performance of the developed guide device, the target performance was satisfied in the watertight test, salt spray test, vibration test, and durability test.
