wall thickness reduction meaning in Chinese

壁厚减薄率

Influences of the tube wall thickness reduction after hydraulic expanded joint on the residual contact pressure
液压胀接后管壁的减薄对残余接触压力的影响
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
通过数值模拟研究获得了包括防皱块和芯棒形式、尺寸和安装位置在内的模具结构对制件成形质量的影响规律；结合对理想纯弯曲的理论分析，研究获得了相对弯曲半径r / d 、相对壁厚t / d对制件主要质量指标之一的最大壁厚减薄率的影响趋势和大小。
