摘要
对于实际工程问题 ,机构自由度的确定往往不能简单地套用计算公式 ,除了需要综合考虑复合铰链、局部自由度和虚约束等问题外 ,还必须具体问题具体分析。本文讨论了一种特殊情况下的机构自由度计算问题 ,并给出了相应的计算方法。
The calculation formulas of degrees of freedom of mechanism sometimes can not be used simply for reality engineering problems. Except considering compound hinges, passive degrees of freedom and redundant constraints etc, it must be specifie analyzed to specific problem. The article discusses the calculation of degrees of freedom of mechanism in special conditions, and gives the corresponding calculating methods.
