초록
Unlike K9A1 and K55A1 (self-propelled artilleries), K105A1 has two outriggers that support the ground to alleviate the shooting shock. In the operation test and evaluation (OT&E) of K105A1, however, a left-sided outrigger stopped with a noise when operating at an inclination of around 10.2°. To determine the cause of this problem, the outriggers were disassembled and scrutinized in terms of a gap between inner- and outer-tubes, performance of wear rings mounted on the tubes, a driving motor's capacity and surface roughness of the tubes. It is identified that the failure is mainly due to a narrow gap and following friction between the tubes. Accordingly, we increased the gap by changing the design of components while sealing off the tubes so that no foreign bodies enter. The result of new field tests demonstrates that our solutions are effective.
