展開 我們為什么要做虛擬路譜激勵的整車路躁仿真？

3.基于路譜的整車路躁分析，研發需求的必然結果
仿真最大的優勢就在于提前預知性能水平，及早做出判斷和反饋，盡量在研發前期把不合適的不匹配的結構設計扼殺在搖籃里面。我們所做的部件、子系統的性能目標，最終的目的是保證整車的性能目標，但這里有最關鍵的部品——輪胎。不同的輪胎性能有很大的不同，輪胎的模型是否可能直接匹配底盤和車體，是否會由于輪胎的振動特性造成整車的振動和噪聲，這都需要驗證。現在的做法就像是兩個人相互埋頭做事情，一邊根據要求設計輪胎，一邊依據系統目標、部件目標設計底盤和車身，但這兩個組合起來的性能如何，卻要等到騾子車采集到spindle才能仿真驗證，從研發的需求來看，最好是能在更早之前就能知道，越早提前預知，也就越早得到反饋，部件越早可以變更，時間周期上、研發成本上也能大大降低開支。另一個，就算能容忍spindle加載方法求得整車路躁，也不能評價出底盤的優劣，因為逆矩陣方法求得的反力，已經吃掉了底盤建模的誤差，所以基本無從評價底盤結構的好壞。所以，要全面評價輪胎、底盤和車身，基于虛擬路譜激勵的整車路躁方法是研發需求的必然結果。

展開 淺談有限元方法的核心思想
有限元和計算機發展共同構成了現代計算力學 （Computational Mechanics）的基礎。有限元法的核心思想是“數值近似”和“離散化”， 所以它在歷史上的發展也是圍繞著這兩個點進行的。
1數值近似
由于在有限元法被發明之前，所有的力學問題和工程問題中出現的偏微分方程只能依靠單純的解析解（Analytical Solution）得到解答。這種方法對數學要求很高，而且非常依賴于一些理想化的假定（Assumption）。比如在土木工程中梁柱計算中出現的平截面假定、小應變假定、理想塑性假定。這些假定其實是和實際工程問題有很大偏差的，而且一旦工程問題稍微復雜一些我們就不能直接得到解析解，或者解析解的答案誤差過大。而有限元法把復雜的整體結構離散到有限個單元（Finite Element），再把這種理想化的假定和力學控制方程施加于結構內部的每一個單元，然后通過單元分析組裝得到結構總剛度方程，再通過邊界條件和其他約束解得結構總反應。總結構內部每個單元的反應可以隨后通過總反應的一一映射得到，這樣就可以避免直接建立復雜結構的力學和數學模型了。其總過程可以描述為：
總結構離散化 — 單元力學分析 — 單元組裝 — 總結構分析 — 施加邊界條件 — 得到結構總反應 — 結構內部某單元的反應分析
在進行單元分析和單元內部反應分析的時候，形函數插值（shape function interpolation）和 高斯數值積分（Gaussian Quadrature）被用來近似表達單元內部任意一點的反應，這就是有限元數值近似的重要體現。一般來說，形函數階數越高，近似精度也就越高，但其要求的單元控制點數量和高斯積分點數量也更多。另外單元劃分的越精細，其近似結果也更加精確。但是以上兩種提高有限元精度的代價就是計算量幾何倍數增加。
