【Abstract】 A promising approach to variable relation parametric based on the graphic structure modelon has been put forward . The paper gives a parametric description model of graphic structure modelon , and relating method for different graphic structure modelon based on variable constraint . In the same time , with the aim of practicality engineering , the self-discipline constraint in modelon and relating constraint between two modelon are given . Finally , with the tool of variable and relating dbase , We give the solving method of variable relating and variable-driven among different graphic structure modelon in a part , and double-acting variable relating parametric method among different parts in which assembly relation are existed.更多还原
