| Popis: | 従来，自動車の車体の構成部材の殆どは，金属で作られていた．しかし，金属に代わり重量やコスト面、安全性、形状自由度などで優れたプラスチックの使用が増加しているが，その疲労寿命を予測する方法はまだ確立されていない．そこで，本研究では，樹脂素材のS-N線図を作成し，それを使用して樹脂構造体の疲労評価を行った結果，実際の疲労試験結果と近い疲労寿命を予測することができた． In the past, most of the body components for cars were made of metal; however, in recent years, the usage of resin is increasing. The reason being resin is superior in weight, production cost, material cost, safety, durability, and shape freedom compared to metal, but a method to estimate the fatigue life of resin structure has not been established. So in this study, S-N curve of resin specimen was made, and using it, fatigue life of resin structures were predicted. As a result, predicted fatigue lives show fairly good agreement with measured lives on fatigue test. |
