Floor material impact load measurement method and floor material safety evaluation method

摘要

PROBLEM TO BE SOLVED: To provide a floor material impact load measuring method for simulating the impact load when a user falls on the floor material in order to obtain the relationship between the rigidity of the floor material and the risk of femoral fracture. A method for simulating the impact load applied to the femur of a user when the user falls on the floor material, which is placed on top of an evaluation floor material 9 made of the same material as the floor material. The cushioning material 10 arranged and formed of a material simulating human soft tissue, a weight 11 having a weight based on the pressure distribution applied to the trochanter of the femur by a simulated fall, and a shape simulating the trochanter The hitting portion 19 is Then, the integrated weight and striking part are dropped at a predetermined drop height based on the simulated fall height, and the weight gives a shock to the evaluation floor material with the striking part in contact with the cushioning material. The impact load generated on the floor material is measured by the load measuring means 8. [Selection diagram] Fig. 3
