摘要
在雨刷刷拭的過程中，雨刷在擋風玻璃上分布壓力會受到彈片弧形、玻璃曲率以及雨刷截面之影響。一般雨刷的下壓力為14~17N/m，而設計上要求雨刷各點的壓力要在10N/m~20N/m之間為最佳。本研究主要建立無骨雨刷下壓力分布的模擬技術，使用的數值方法為有限元素法，研究中以17N/m為雨刷的下壓力，探討雨刷膠條截面、玻璃曲率、摩擦係數與攻擊角等參數對雨刷下壓力分布的影響。計算結果顯示:本文所計算的壓力分布結果與實驗量測之結果趨勢相近。本文所建立的模擬技術可以用來分析雨刷在擋風玻璃各處之壓力分布，用來預測彈片設計弧形的優缺點與並評估擋風玻璃各位置的刷拭品質。

During the wiping process, the distribution pressure of the wiper on the windshield is affected by the profile of the vertebras, the curvature of the windshield glass, and the shape of the blade. In general, the down-force of the wiper is 14~17N/m, and the design requires that the pressure of each point of the wiper be between 10N/m and 20N/m. In this study, the emphasis is put on the development of the simulation technique for pressure distribution of flat wiper utilizing the finite element method. In the study, the down-force of the wiper with 17N/m is discussed. The effect of blade shape, glass curvature, frictional coefficient and attack angle on the pressure distribution of the wiper, are simulated and eludicated. The results show that the pressure distributions calculated in this paper are concurred with those of the experimental measurements. The simulation technique established in this paper can be used to analyze the pressure distribution of the wiper on the windshield. It is used to verify the feasibility of the profile design of the vertebras and to evaluate the wiping quality of each position of the windshield.
