    液壓脹接后管壁的減薄對殘余接觸壓力的影響
  2. 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。
