| 摘 要： | 要实现平面机构的确定运动，就必须保证机构的自由度数大于零且机构自由度数等于机构的原动件数，因此准确求出平面机构的自由度数至关重要。通过对平面机构在局部自由度、虚约束、多环等一些特殊情形下的自由度求解分析，证明了欧阳富等人提出的平面机构自由度数求解公式的正确性和实用性，并确定了其参数在实际计算中的选取原则。

| Abstract: | To achieve the determination of plane mechanism movement, it is necessary to ensure that the number of degrees of freedom of mechanism is greater than zero and equivalent to the original moving parts number. Thus calculating accurately the degree of freedom for planar mechanism is crucial. By solving degree of freedom for planar mechanism such as partial degree of freedom, redundant constraint and multi-loop, the correctness and the practicality of a new calculating formula of degree of freedom for plane mechanism presented by Ouyang Fu are verified, and choosing principles for parameters are established. |
