Abstract
This study establishes the measurement method of the slipperiness by pets. This study is necessary to clarify the method to evaluate safety of pets. First actions are interview to the animal doctors and experts at houses, the selection of subject pets (“Dog” is selected.), and collection of information about soles of dogs. Next, angles θ2 which the subjects start to slip are searched by ramp method with 16 subject dogs and 16 kinds of floor samples. Then, coefficients of slip resistance (C.S.R') of the floor samples are searched with ONO · PPSM (ONO · Portable Pull Slip Meter) by various slider materials and vertical loads (W). Also, the relations are investigated between these C.S.R' and tan θ2. As results, it is an appropriate measurement method of slipperiness of dogs to use a slider material with hemp fabric over foamed rubber sheet and W=49N.
