2、创建配合关系- e5 {8 G% b& h' k& g! Y
a.通过函数UF_ASSEM_init_mc()初始化约束;
I0 g9 R" }6 h# x2 M c. Z* Gb.定义约束关系,即填写结构UF_ASSEM_constraint_s中信息; E; S: z8 t/ Y' u2 b7 m
装配中各部件间的配合关系是通过装配约束关系来实现的。装配约束是指一个部件到另一个部件的约束,将部件A配合到部件B上,则部件A称为主动件(from),部件B称为被动件(to),在约束求解过程中,被动件在装配空间中的位置固定,而主动件将变换姿态到满足装配约束位置上。组成配合关系的约束之间不能存在几何关系上的矛盾,也不能形成循环定义。
