題があった。Conventionally, as described above, since an actual vehicle is run on the ground or on a continuous road surface to carry out a running test of an endless track device, many running test data are obtained. It takes time to reduce the development efficiency of the infinite track device. In addition, when an actual vehicle is run on the ground and a running test is performed, the running state changes depending on the soil type, hardness, water content, and the like. For example, when focusing on running vibration, the state of the ground changes depending on the measurement date and the measurement time. Therefore, there is a problem that it is difficult to obtain highly accurate vibration data.
