Examples
- Since the phase transformation behavior of tini thin film has a great influence on the properties of micro - actuator , both ti - rich and ni - rich tini thin films " phase transformation behavior were studied in this stud ) "
本文从微驱动材料tini薄膜的相变行为对微驱动器性能影响出发，采用电阻法、 dsc 、 xrd 、 tem等手段，研究了tini非晶薄膜晶化过程、热处理、热循环以及预变形等对tini薄膜相变行为的影响。 - Abstract : in this paper , the effect of pre - stress on peen - forming is studied by experiments , the results show that pre - stress can change the relationship between pre - deformation and pre - stress shot peen deformation , and that 0 . 05 % 0 . 1 % pre - strain is comparetively suitable to improve the spanwise rectilinearity of shot peen - forming configuration surface
文摘:对预应力喷丸成形进行了试验研究，指出预应力可以改变其对应的预变形与预应力喷丸变形之间的大小关系，在以改善喷丸型面纵向直线度为主要目的的预应力喷丸成形中，预应变取值0 . 5 / 1000 1 / 1000较为适宜。 - The 3d model of mold is analyzed in 3d fem by using ugh . base on the analyses result , some danger structure of the model have been found and some suggestions of the mold modification are given . since doing a lot of research about the 3d cadvcae technology , a 3dcad system of selecting mold for aluminum material have been developed and the method of analyzing the 3d model is provided in this paper
然后，为了能真实地模拟实际生产过程，进行铝与模具钢在一定表面粗糙度、不同温度条件、不同润滑接触状态下的最大静摩擦系数实验，总结摩擦系数随温度变化的规律性和取值范围；最后，应用ug 17 . 0三维有限元cae模块进行模具三维力场分析，根据三维有限元的结果分析，对模具危险部分进行预变形的处理和优化，改善模具受力变形的状况。
