Structure Topology Optimization Design of Brake Pad in Large Megawatt Wind Turbine Disc Brake

摘要

The brake pad of disc brake, as an actuator while wind turbine braking, plays an important role in braking system. For seeking an optimum structure of brake pad, its mechanical model during braking process of large megawatt wind turbine in actual working circumstance is established in this paper. Accordingly, model of topology optimization is figured out. Based on the results of topological optimization, a new structure of brake pad is analyzed and a new design plan combined with actual working circumstance is suggested. Testing about new structure which has been done in this paper assures the accuracy.
