A constrained topology optimization methodology based on budget constrained min-cut
A constrained topology optimization methodology based on budget constrained min-cut
Purpose: The purpose of this paper is to propose a novel methodology based on budget constrained Min-Cut theorem to solve constrained topology optimization (TO). Design/methodology/approach: This paper establishes a weighted network with budget, which is derived from the sensitivity with respect to the constraint function. The total budget carried by the topology evaluates the extent to which the constraint is satisfied. By finding the Min-Cut under budget constraint in each step, the proposed method is able to solve constrained TO problem. Findings: The results obtained from a magnetic actuator including a yoke, a coil and an armature have demonstrated that the proposed method is effective to solve constrained TO problem. Originality/value: A novel methodology based on budget constrained Min-Cut is proposed to solve constrained TO problem.

Abstract

Design/methodology/approach: This paper establishes a weighted network with budget, which is derived from the sensitivity with respect to the constraint function. The total budget carried by the topology evaluates the extent to which the constraint is satisfied. By finding the Min-Cut under budget constraint in each step, the proposed method is able to solve constrained TO problem. Findings: The results obtained from a magnetic actuator including a yoke, a coil and an armature have demonstrated that the proposed method is effective to solve constrained TO problem. Originality/value: A novel methodology based on budget constrained Min-Cut is proposed to solve constrained TO problem.
