In the automotive industry, the platinum titanium anodes (Pt/Ti anode) play a significant role in electroplating of chromium coating on the vehicle’s shock absorber piston rod. In this paper, the structure of Pt/Ti anode was designed to obtain high quality and save time for the electroplating process. The structure of anode was designed in 2D & 3D modeling and analyzed by CATIA and ABAQUS program, respectively. The structural modeling of the anode was analyzed and carried out using a finite element method (FEM) by applied various loads. The manufacture anodes were installed in an electroplating bath in order to test the efficiency of chromium coating on shock absorber piston rod and safety of anode structure. The results presented indicate that the structural analysis is safe after applied loads due to the allowable stress is higher than the maximum equivalent stress about 4 times, and the chromium coating test obtained high-efficiency results.

쇽옵서버 피스톤로드(shock absorber piston rod)는 자동차의 충격과 진동의 흡수에 작용하는 자동차 현가장치(sus-pension equipment)부품의 일종이다. 피스톤로드는 자동차 충격흡수에 매우 밀접한 영향을 주기 때문에 제조에 있어서 고도의 정밀도와 표면 매끄러움이 요구된다. 피스톤로드의 제조공정은 선삭, 홈가공, 밀링, 건조 등 여러 공정으로 구성되는데, 여기서 품질불량에 가장 크게 영향을 주는 공정은 선삭공정(lathing
