  displacement conversion
Since the transducer features an independent and interchangeable force to displacement conversion system, different force ranges can be realized by inserting force conversion systems with different compliances.
      
To maintain unity gain, the voltage to displacement conversion was done after the plant model in the control loop.

In this paper, the shortcomings in Burdekin COD design curve are analysed and the formula of transformation derived from EPRI's engineering computation method for obtaining the original crack tip opening displacement is established. A practical example for examining whether the Burdekin COD design curve is applicable was calculated and it is shown that the prediction of Burdekin design curve for failure assessment Of tough material is rather conservative. Therefore, in safety assessment of structure contained...

In this paper, the shortcomings in Burdekin COD design curve are analysed and the formula of transformation derived from EPRI's engineering computation method for obtaining the original crack tip opening displacement is established. A practical example for examining whether the Burdekin COD design curve is applicable was calculated and it is shown that the prediction of Burdekin design curve for failure assessment Of tough material is rather conservative. Therefore, in safety assessment of structure contained defects, the application of Burdekin curve will suffer restriction.

分析了 Burdekin COD设计曲线的不足点,建立了由 EPRI工程计算方法求原裂纹尖端张开位移的转换公式,藉以考查Burdekin设计曲线的保守程度。文中的实例指出:Burdekin设计曲线只适用于以脆断为主要破坏形式的各种构件的预测,而对于以延性撕裂为主要破坏形式的构件,设计曲线的预测偏于保守,在安全评定的应用上受到限制。

This paper describes a new method for determining density from differential interferograms, which was developed by the author. This method can be called "fringe shift transform method". Using this method, the fringe shift function of a differential interferogram is first transformed into the fringe shift function of the corresponding absolute interferogram. Then using the existing methods of calculating absolute interferograms, we can determine the density distribution of the flow field. When the new method...

This paper describes a new method for determining density from differential interferograms, which was developed by the author. This method can be called "fringe shift transform method". Using this method, the fringe shift function of a differential interferogram is first transformed into the fringe shift function of the corresponding absolute interferogram. Then using the existing methods of calculating absolute interferograms, we can determine the density distribution of the flow field. When the new method and two existing methods are applied to a differential interferogram of an axisymmetric flow field, the results obtained are consistent and coincide with the calculating result of aerodynamic theory Further, the method is extended to three dimentional density fields. Thus this indicates the possibility for using the differential interferometer to three dimentional flow field.

本文描述作者发展的一种计算差分干涉图的新方法——条纹位移转换法。该方法,首先将差分干涉图的条纹位移函数转换为绝对干涉图的条纹位移函数,然后用计算绝对干涉图的现有方法,计算出密度分布。将此方法同原有方法一起应用于轴对称流场的差分干涉图,计算结果一致,并同气动理论计算数据相符。最后又将该方法推广到三维流场,这就预示出将差分干涉定量测量应用于三维流场的可能性。
