摘要
提出一种研究空间6杆回路过约束问题的完全解析法，只用4个基本方程并结合轮换就可判定回路的过约束性，同时可得到封闭条件，进而导出输入输出关系。用该法可方便导出Bricard三面体机构的封闭条件及输入输出关系，并完善了一个已有4R2P过约束机构的封闭条件及输入输出方程的解析式。
A complete analytical method to study six link overconstrained mechanisms by using only four basic equations combined turning technique is presented. Meanwhile, closure conditions can be obtained and I-O equations can be further deduced. By using this method, the closure condition and I-O equations of the Bricard trihedral mechanism can be derived expediently. Also, the closure condition and I-O equations of a known 4R2P overconstrained mechanism are deduced for the first time.
