制造模式变迁的动力机制及其特征分析 总被引:1,自引:1,他引:0
制造模式变迁过程受制于三类因素,即制造模式现有状态、制造模式的四大基本维度(技术与方法、文化、组织结构以及和谐管理)和外部环境中的随机涨落因素。该过程表现出非平衡相变、对称性破缺、分叉等特征。当新的制造模式形成时,其研发投入、文化、组织结构及其管理、知识调配都须有很大的变动和调整。 相似文献

Hole-drilling method is one of the most convenient methods for engineering residual stress measurement. Combined with moiré
interferometry to obtain the relaxed whole-field displacement data, hole-drilling technique can be used to solve non-uniform
residual stress problems, both in-depth and in-plane. In this paper, the theory of moiré interferometry and incremental hole-drilling
(MIIHD) for non-uniform residual stress measurement is introduced. Three dimensional finite element model is constructed by
ABAQUS to obtain the coefficients for the residual stress calculation. An experimental system including real-time measurement,
automatic data processing and residual stresses calculation is established. Two applications for non-uniform in-depth residual
stress of surface nanocrystalline material and non-uniform in-plane residual stress of friction stir welding are presented.
Experimental results show that MIIHD is effective for both non-uniform in-depth and in-plane residual stress measurements.
