Automobile Door Opening Angle Control System has been invented for limiting the opening angle at emergency environment or protecting door scratches while a passenger operates a door. We used topology optimization technique for the link part which transmits the load in the system, and it can also substitute the door impact bar. The system itself can be directly commercialized and equipped to all kinds of automobile door systems.

Brake noise is one of the cacophony occurring at any car during the driving. This noise is caused by the vibration between the rotor and the brake-pad. A vibration frequency ranges from 300 to 500Hz as a Moan frequency. In this study we investigate the Topology Optimization of the brake pad to eliminate the frequency inducing the Moan Noise. We simulated the finite element model and found out the nodes in which the Brake Moan occurs the most and we regarded the boundary and its relationship between the brake pad and the rotor as a spring coefficient k. With the binary set of the spring coefficient k, we finally used Response Surface Method to get the optimal topology of brake pad and it's shape to reduce the Brake Moan. The final result remarkably shows that brake moan noise can be eliminated by changing the brake pad topology.<br/> <br/>
