| Popis: | 本研究では，日本における建築物外装材の耐衝撃性能の標準仕様や試験方法の策定に資するため，高速で飛来する飛散物を模擬する加撃体を射出し，外装材の耐衝撃試験を行うためのエアーキャノンを作製した．エアーキャノンの設計にあたっては，アメリカ合衆国やISO基準に準ずる耐衝撃性能試験を行えるようにした．本報告では，外装材の耐衝撃性能を評価する既存の試験・評価方法を概説するとともに，作製した装置の性能試験結果について述べる We manufactured an air-cannon, that is a missile-propulsion device, for the impact resistant test of cladding against windborne debris. The air-cannon consists of a compressed-air supply, pressure control and release valves, a barrel, a support frame and a speed-measuring system. Sets of photoelectric sensors mounted on the barrel are used for measuring the speed of the missile. The cannon is capable of propelling a missile at a specified speed and orientation towards a specified impact location. We calibrated the speed measuring system by a high-speed video camera. The fastest speed was 75m/s for a 3kg lumber. Tolerances for the measured impact speed were satisfied the specification of ISO16932. |
