ブレーキ鳴き低減を目指したディスクブレーキの構想設計法: First Order Analysisの考え方に基づく簡易解析モデルを用いた設計評価尺度の構築

摘要

Minimizing brake squeal is one of the most important issues in the development of high performance braking systems. Recent advances in numerical analysis such as finite element analysis have enabled sophisticated analysis of brake squeal phenomena, but current design methods based on such numerical analysis still fall short in terms of providing performance measures for minimizing brake squeal, of high performance design drafts at the conceptual design phase. This paper proposes a conceptual design method for disc brake systems that aims to reduce brake squeal by tailoring the shapes of the brake system components based on the concept of First Order Analysis (FOA). First, the relationships between brake squeal performance and the geometry and characteristics of various components is clarified using a simplified analysis model. Next, a design performance measure is proposed for evaluating brake squeal, and a method for deploying component designs based on this measure is discussed. Finally, a practical design example is provided to confirm that the proposed method can yield useful designs for high performance braking systems.%現在の機械製品の開発において，CAE（Computer Aided rnEngineering）は必要不可欠となっている．コンピュータ技術のrn飛躍的な発展に伴い，CAEは試作品を作成することなく，製品rnの性能を定量的に評価し，必要な場合には最適設計技術によりrn性能改善を行うことができる．
