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 without causing variations in the rate or in the angle of a needle penetration, and that also allow a measurement to be done on one sample in more than one point.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: an attachment mechanism 3 attached to a side of a columnar sample 2; and a penetration mechanism 4 provided to the attachment mechanism 3. The penetration mechanism 4 includes: a penetration needle 43, which can go ahead or go back; and measurement means for measuring a penetration resistance load and a penetration depth when the penetration needle 43 penetrates the sample 2.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可能とし、かつ、１つの供試体に対して複数点における測定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】柱状の供試体２の側面に装着される装着機構３と、装着機構３に設けられた貫入機構４とを備える針貫入試験装置１とこれを利用した針貫入試験である。貫入機構４は、進退可能な貫入針４３と、貫入針４３を供試体２に貫入させたときの貫入深さおよび貫入抵抗荷重を測定する測定手段とを備えている。【選択図】図１
