摘要： A method of detecting a decrease in a tire air pressure based on wheel rotation information obtained from tires attached to a four-wheel vehicle. The method includes: a step of calculating wheel rotation information obtained from the respective wheel tires; a step of computing the first to the third judgment values DEL1, DEL2, and DEL3; a step of storing the wheel rotation information, the first judgment value, the second judgment value, and the third judgment value; a step of setting judgment conditions for the first judgment value, the second judgment value, and the third judgment value with regard to the respective wheel tires; and a step of judging, based on the judgment conditions, a decrease in the air pressures of the respective wheel tires. The step of setting the judgment condition sets threshold values used for the judgment conditions depending on a status of a road on which a vehicle runs, a turning level of the vehicle, or a level of the running of the vehicle running on an uphill or a downhill.

At step 2, a stress and a strain component of each element of the golf ball model and coordinate values of the nodal points of each element are outputted; and a value of a stress and a strain of each of six components of each element are computed momently. At step 3, the relationship between the stress and the strain of each component of each element is found from the value of the stress and the strain of each of the six components; and energy loss values of each element are computed. At step 4, the energy loss value is computed for all elements included in the golf ball model; the computed energy loss value is read by a visualizing software; and the energy loss of the golf ball model is visualized.
