Feng Lv, Linna Bai, Limiao Wang
According to physical equation, it respectively calculates 38mm, 40mm diametersÂ’ table tennis arc, strength, speed, rotation, drop point, time, clarity and its change rate. And then, use above factors to establish analytic hierarchy process model, athlete experience qualityÂ’s criterion layer is composed of arc, strength, speed, rotation, and drop point, and get that small ball has best experience quality to athlete while big ball experience quality is the worst. Similarly, audienceÂ’s criterion is composed of round numbers, clarity and time, and get big ball has best appreciation quality to audience, and small ball experience quality is the worst. Finally it gets table tennis ideal diameter is 41mmby analog simulation
