【Abstract】 The assembly modeling and assembly constraint for the dies were proposed.The motion freedom analysis and calculation method were constructed to correctly and effectively solve the assembly constraint without the requirement of simultaneous solution to the non_linear constraint equations.In the mean time,the method also well solved the under_constraint and over_constraint problems in the assembly,which makes it easier to realize the intelligence and automatization of the assembly design process.更多还原
