自動車のドアラッチシステムにおけるケーブルとロッドのロバスト設計

抄録

The　functional　requirement　of　an　automobile　latch　system　is　to　assure　that　the　door　or　tail　gate is　in　a　closed　position　for　controlled　releases.　The　variation　of　release　efforts　for　a　door　latch system　affects　customer　satisfaction,　and　it　is　related　to　the　operating　efficiency.　The operating　efficiency　for　an　automotive　latch　system　is　defined　as　the　ratio　of　the　output　energy at　the　handle.　The　load　transfer　between　the　handle　and　the　latch　relies　on　cables　or　rods. A　robust　case　study　was　conducted　to　investigate　the　door　latch　linkage　system　under　various noise　conditions:　temperature,　humidity,　salt,　dust,　abusive　usage,　pitching　angle　and　yawing angle.　Through　this　study,　design　guidelines　have　been　developed　to　improve　the　robustness and　operating　efficiency　of　a　door　latch　linkage　system.
