Its reliability has been tested though examining. the influence laws of mould structure, including wiper die and the style, size and installed position of mandrel, have been studied. combined with the theoretical analysis of perfect pure bending, the tendency of relative bending radius r / d and relative wall thickness t / d to one of the major quality target - the maximum wall thickness reduction ratio is also studied
通過數值模擬研究獲得了包括防皺塊和芯棒形式、尺寸和安裝位置在內的模具結構對製件成形質量的影響規律；結合對理想純彎曲的理論分析，研究獲得了相對彎曲半徑r / d 、相對壁厚t / d對製件主要質量指標之一的最大壁厚減薄率的影響趨勢和大小。 -
The optimization selection and comparison have been conducted on the ratios of major structural dimensions of ball cage patterned constant speed universal joint namely the ratio between central circle diameter of steel ball and ball diameter, the ratio between outer diameter of universal joint and diameter of graduation circle of inner sleeve spline and the ratio between eccentricity of ball cage patterned constant speed universal joint and central circle radius of ball
對球籠式等速萬向節的主要結構尺寸即鋼球中心圓直徑與鋼球直徑之比、萬向節外徑與內套花鍵分度圓直徑之比，以及球籠式等速萬向節的偏心距與鋼球中心圓半徑之比進行了優化選擇和比較。 -
Base on the finite element method, the major factors that affect the work behavior of self - expanded pile are studied, these major factors include the modulus of compressibility of pile side soil, bearing stratum soil and substratum soil ; the ratio of length and radius of pile ; the ratio of expanded body ' s radius and pile ' s radius ; the depth into bearing stratum of pile end ; load value and so on
然後通過有限元法分析了影響自擴樁工作性狀的主要因素，研究了樁周土、持力層和下臥層土的性質、長徑比、擴徑比、樁端進入持力層深度、荷載大小等因素對自擴樁荷載傳遞特性的影響。
