| Abstract: | Based on the minimum resistance law of framework,the rotational principle of pole framework of changing degrees of freedom mechanism(CDFM) is researched into,considering the factors of friction and gravity,and the formula about the rotational principle of pole framework is put farward.Based on Taylor series,the friction torque is linearized in consideration of the friction of the ratational.As an example,the orders of planar five-bar mechanism was analyzed in detail. |

| Keywords: | minimum resistance law of framework changing degrees of freedom rotary planar mechanism Taylor series linearize planar five-bar mechanism |
