Above elaborated explains two points : first, although there are many advantages of the computer simulation, but can not be completely divorced from or replace tests, finally is must depend on experiments performs to confirm. second, computer simulation is a trend to replace test, but the key question is to resolve the model error. in view of former, the author of this study focusing on the principle of emphasize the test, researched the techniques factors of the components of the vehicle body works on the anti - collision capability
殘余應力會有一定程度的釋放，材料的強化會隨之變化，那麼以往的研究中之考慮了沖壓成型階段帶來的厚度分佈不均和殘余應力、應變，卻忽視了由於高溫固化時溫度升高所帶來的殘余應力釋放，這樣最終會直接影響到碰撞模擬模擬的精度，從而導致車身結構的碰撞安全性指標的不精確。 -

The idea behind it is to approximate the object with a simpler bounding volume that is a little bigger than the object. in building hierarchies on object, one can obtain increasingly more accurate approximations of the objects. so during traversing bounding volume hierarchy, it speeds up collision detection by prune away primitive pairs, which will not intersect clearly though rapid intersection test between bounding volumes and just deal with those whose bounding volume is intersected
層次包圍盒方法是解決碰撞檢測問題固有時間復雜性的一種有效的方法，它是用體積略大而幾何特性簡單的包圍盒來近似地描述復雜的幾何對象，並通過構造樹狀層次結構來逼近對象的幾何模型，從而在對包圍盒樹進行遍歷的過程中，通過包圍盒間的快速相交測試來及早地排除明顯不可能相交的基本幾何元素對，而只對包圍盒重疊的部分元素進行進一步的相交測試，以提高碰撞檢測的速度。 -
