- Abstract
- The parking gear is very important part of automotive because it is related to safety. Nonlinear gear groove of parking gear is used to enlarge the contact area between parking gear and pawl. The die has been widely applied for many industrial parts such as machine, automotive and so on. The purpose of this study is to investigate the stability of upper and lower dies by using numerical analysis. As the results, the lower die was weaker than the upper die in this study, and the lower die showed that it should be used within 500ton in terms of safety factor. Further the most weak point of lower die was low location in front of gear. Its minimum value of safety factor was 0.578 in case of 4000ton of press load, therefore, this weak point was needed to be reinforced.
