| dc.description.abstract | As Eco-conscious is taken more seriously by people, the effective use of fuel is gradually valued by the world. Among them, battery life of fuel saving is a key factor for adding value to automakers and attracting consumers. In the past configuration of the disc brake system, considering the braking efficiency and braking strength, there have slight residual resistance while the brakes are not activated. It is mainly related to the design of the piston retraction of the disc brake caliper. In addition, this residual resistance causes unnecessary fuel consumption for electric motor and general gasoline motor. This issue is gradually criticized by major automakers, and gradually included in the failure mode and effect analysis, which is regarded as a problem that must be overcome. To overcome this issue, new technology specification disc brake systems would be developed. In the past, R&D designers mostly developed new products based on past experienced and trial and error methods. However, this method has caused the traditional machinery industry to lack a systematic development process in the new product development process and verification, moreover, the development cost is often not control ideal.
This study will develop new technology specification for retraction distance of disc brake pistons. Due to unique quality characteristics, too small or too large retraction distance of pistons would adversely affect the braking system. Therefore, the goal of this research is to overcome the issue-Residual resistance in failure mode and effect analysis(FMEA) as a starting point, using Taguchi method to overcome the problem of sliding resistance in failure mode analysis. And expected to reduce the occurrence of two seriously failure modes and select the best parameter design. The impact of the product will then achieve a robust design. Finally, discuss the improvements and contribution of the Taguchi Method experiment and results to the enterprise. | en_US |
