Based on the nonlinear, elastic-plastic finite element method theory, the modeling approach of the numerical simulatioin of SPIF was studied firstly in this project.

本课题首先基于非线性、弹塑性有限元理论方法，对金属板材单点渐进成形过程的数值模拟的建模方法进行研究。

In SPIF process, the loading trajectory is complex and long, the thinning of the sheet thickness is dramatic, and the local deformations are accumulated. So, there are some difficutis in the numeriacla simulation of SPIF. For example, the modeling of SPIF is difficult and the computational efficiency is low.

金属板材单点渐进成形由于自身的特点，如成形过程载荷加载轨迹复杂且长、板材厚度的剧烈减薄变化、以及局部变形累积等，使得对其进行有限元法数值模拟存在建模难度大、计算效率低等难点问题。

An attempt was made to remove color from simulated wastewaters containing Acid Scarlet GR and Reactive violet K-3R by cloud point extraction using a nonionic surfactant of Triton X-114. The influence of the concentrations, equilibrium temperature and equilibrium time on the extraction efficiency was tested. The experimental results show that the extraction efficiency to dye increases with increasing concentration of TX-114 and salt or decreasing initial dye concentration.

In this paper Ⅰ successfully applied these methods to fault diagnosis, and presenting some new innovative machinery fault diagnosis method; First Ⅰ present a new gear wornout fault diagnosis method, this method use the vibration signal's time-frequency attribute and instantaneous phase undulation to accurately detect gear's fault, and by comparing with the traditional frequency domain analysis method, this method reveals that many nonlinear and nonstationary characteristic exist in gear's vibration, this tell us that if we use frequency domain analysis method without pay attention to the signal's characteristic, we could get wrong diagnostic result; Then Ⅰ present a new bearing fault diagnosis method, this method use ATVFD and Hilbert transform to do envelop demodulation,Ⅰ analyze the envelop with time-frequency method and find out that this method is more accurate then traditional method.Ⅰ also explain that the modulation of the fault to the carrier wave may also be non-stationary and nonlinear; Finally Ⅰ present a cylinder pressure measurement method of diesel engine by means of vibration, cylinder pressure is an important parameter of diesel engine fault diagnosis, the pressure measuring is simplified a lot by this method,Ⅰ also use the ATVFD and time-frequency analysis to realize it.

本文中将上述理论方法成功地应用到故障诊断中去，提出了几点创新性的诊断方法；提出了一种齿轮磨损故障诊断的新方法，该方法利用振动信号能量的时频域分布特征与瞬时相位波动特征可以进行精确的齿轮故障诊断，并通过与传统的频域诊断方法的比较，揭示出齿轮振动中存在的明显的非线性与非平稳特征，说明了不加选择地利用频域分析方法进行齿轮故障诊断很可能会得到错误的诊断结果；提出了一种轴承故障诊断的新方法，该方法利用ATVFD分解与Hilbert变换进行包络解调，并对解调得到的包络信号进行时频域分析，可以实现更加准确轴承故障诊断，说明了故障对载波信号的调制往往也是非平稳与非线性的；提出了一种利用振动信号进行柴油机汽缸内压力检测的新方法，柴油机汽缸压力的变化是柴油机故障诊断的重要参数，利用振动方法可大大简化汽缸压力的检测过程，该方法也是综合利用ATVFD分解与时频域分析方法实现的。
