1、装入部件! x& @. R- P; B0 c, d# o1 I
通过函数UF_ASSEM_add_part_to_assembly()指定部件装入的位置 、姿态等信息,实现在装配体中装入一个部件功能; |- G5 u& v6 t$ y7 N d5 C* g& s/ b' z6 R
4 p6 b, j" k$ X/ i4 ]% ]2 i
2、创建配合关系4 y H$ ~6 C- S' P3 V/ @% G9 W
a.通过函数UF_ASSEM_init_mc()初始化约束;
/ ^ X0 g O( eb.定义约束关系,即填写结构UF_ASSEM_constraint_s中信息;
" M# n. y* R) |1 _) U9 e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。+ v6 K& l6 c i2 k; [6 x
c.通过函数UF_ASSEM_solve_mc()求解约束;
& I2 c3 E1 _/ H2 U% vd.通过函数UF_ASSEM_apply_mc_data将约束应用到装配体上;2 S+ ^1 Z' `5 C* H
e.通过函数UF_MODL_update更新模型。
