S1110303 多点センサを用いた巻取りロール内部の軸方向における応力分布測定([S111-03]第20回卒業研究コンテスト(3),機素潤滑設計部門)

Plastic film has recently received attention due to make the flexible lithium-ion secondary battery. Plastic film is produced by Roll to Roll system. In this system, winding process is the final section of the producing line. Wound roll can be stored in a small space. However, plastic film have thickness variation for width direction. Plastic film have the large thickness variation cause trouble in the wound roll. Currently, plastic film have thickness variation is known to cause the stress distribution in axial direction when it was wound. In this research, we manufactured a multipoint sensor and measured radial stress. As a result, it is found that multipoint sensor can be measured the six point's radial stress in the axial direction.
