On the basis of measured results of contact pressure on abundant literature and the computed results in this paper, simplified contact pressure models have been put forward. the finite element program msc. nastran was selected to analyze the response of pavement under the two modelled loads. the effects of axle load and material properties were studied, and the effects of truck load on permanent deformation and fatigue crack were also discussed
本文首先根據輪胎胎面花紋類型的不同,提出接觸面的簡化模型;然後參考相關輪胎與路面接觸壓力的測試結果,並結合本文的測試結果及輪胎與路面接觸壓力的模擬計算結果,提出接觸面內的壓力分佈模型,即輪胎作用於路表的荷載簡化模型;接著利用有限元軟體msc . nastran對瀝青路面在該荷載模型作用下的響應進行計算分析,還討論了軸載的變化及路面材料參數的變化對路面結構響應的影響,並且對車輛荷載對車轍和疲勞裂縫的影響進行探討。
