DEVICE AND METHOD FOR TESTING NEEDLE PENETRATION
To provide a device and a method for testing a needle penetration that allow a quantitative measurement to be done easily and at site without causing variations in the rate or in the angle of a needle penetration.SOLUTION: The present invention relates to a needle penetration test device 1 and a method for testing a needle penetration using the device 1, the device including: a penetration mechanism 3 having a penetration needle 32 and measurement means 33; a chuck mechanism 4 for holding the penetration mechanism 3; and a passage 21 in which the chuck mechanism 4 can move. The chuck mechanism 4 guides the penetration mechanism 3 to a measurement target surface by moving along the passage 21. The penetration needle 32 penetrates the measurement target surface when the chuck mechanism 4 is guided to the measurement target surface. The measurement means 33 measures a penetration resistance load when the penetration needle 32 penetrates the measurement target surface.SELECTED DRAWING: Figure 1
【課題】針貫入時の速度や角度にばらつきが生じることなく定量的な測定を現地にて簡易に実施することを可能とする針貫入試験装置および針貫入試験方法を提案する。【解決手段】貫入針３２および測定手段３３を備える貫入機構３と、貫入機構３を保持するチャック機構４と、チャック機構４が移動可能な通路２１とを備える針貫入試験装置１とこれを使用する針貫入試験方法である。チャック機構４は、通路２１に沿って移動することで貫入機構３を測定対象面に誘導する。貫入針３２は、チャック機構４が測定対象面に誘導された際に測定対象面に貫入される。測定手段３３は、貫入針３２が測定対象面に貫入された際の貫入抵抗荷重を測定する。【選択図】図１
