The result s show th at the relat ve dev at on of roll ng force calculat ed valu e from measured valu e s 1130% ~ 9137% , and the relat ve dev at on of roll ng moment calcu lat ed value from measured value s 31 69% ~ 9175% . The s mu2 lated results of two an d three d mens on al f n t e element model are same bas cally.
