【摘要】 针对传统平面机构自由度计算公式多及计算不准等问题,提出用一个新的公式来替代传统平面机构自由度计算的多个公式,用一个多余自由度λ替代平面机构局部自由度和虚约束两个概念,为平面机构自由度计算提供了简单、准确的计算公式。更多还原

【Abstract】 In view of inaccurate calculation problems involved in many formulas for calculating degree of freedom of traditional plane mechanisms,a new formula is proposed to replace many of the formulas used for traditional plane mechanisms.λ,an extra degree of freedom,is used to replace two concepts of plane mechanisms,partial degree of freedom and virtual constraint degree,which provides a simple and accurate formula for calculating degree of freedom of plane mechanisms.更多还原
