Toolbar

Color Map and Surface Contour toolbar support various features.

  • Import File: It is used to import 3D data file (*.csv). Usually exported from its dialog.

  • Export Files: It is used to export 3D data file (*.csv).

  • Export Image (Clipboard): It is used to copy an image of color map to the clipboard.

  • Export Image (Setting): It is used to make image file of color map.

  • Initialize View (F): It initialize the view status such as zoom. In case of Surface Contour, translate, and light control.

  • Rotate View: It is Surface Contour option. When this option is toggled on, the surface contour slowly rotates. It can be used to demonstrate general view of the surface contour.

  • Translate View(T): It is Surface Contour option. When this option is toggled on, mouse drag operation is changed to translate view. Default mouse-drag operation is rotate.

  • Trace Data: It traces the RPM, Frequency, Magnitude data from the location of mouse pointer.

  • Section View: It is Color Map option. It enables the section view of X and Y-Axis and section view option. With Trace Data option toggled, clicking the color map updates the X, Y-sections. In the Section View, the Phase-angle [Degree] results are shown in each section line.

    • Align to Order Line: It shows a order line in the RPM-Frequency section view. This option is only enable in the RPM-Frequency section view.

    • Show Section Lines: It specifies whether to toggle the section line.

    • Zoom: It specifies the mouse operation in section view plot. Dragging in the section view plot operates as Zoom.

    • Data Trace: It specifies the mouse operation in section view plot. It traces the data from the location of mouse pointer.

    • Fit: It initialize the view status such as zoom.

    • Order Line (Vold-Kalman Filter): It shows the second generation Vold-Kalman Filter result which is an order tracking algorithm based on bandwidth pass filter. It is only enabled in the RPM-Order Section View. If the check box is checked, then the RPM-Magnitude and Phase angle plots are the Vold-Kalman Filter result (X axis: the reference rotational velocity [RPM], Y axis: The Magnitude and Phase of Vold-Kalman Filter result). If the check box is unchecked, then the RPM-Magnitude and Phase angle plots are interpolation result of the 2D map. For more information, refer to the Vold-Kalman Filter.

      • Frequency Bandwidth: It is a bandwidth option of the Vold-Kalman Filter. The default value is set to 1.0/(End Time - Start Time). The bandwidth value should be positive real number.

      • VK Weighting Factor: It is the Vold-Kalman Filter weighting factor. The relation of the Frequency Bandwidth (bw) and the VK Weighting Factor(r) is approximated to below equation. The factor value should be positive real number.

        2-Pole: \({{b}_{w}}=\frac{{{f}_{s}}}{2\pi }(1.58{{r}^{-0.5}})\)

        3-Pole: \({{b}_{w}}=\frac{{{f}_{s}}}{2\pi }(1.70{{r}^{-1.0/3.0}})\)

        Where, \(f_s\) is the Sampling Frequency of the Campbell source data.

        If the radio button is checked to the VK Weighting Factor, then the user-input VK Weighting Factor is directly used for computing the Vold-Kalman Filter. If the radio button is checked to the Frequency Bandwidth, then the solver calculates the Vold-Kalman Weighting Factor using above equation and use it.

        Note

        The maximum diagonal value of the assemble matrix is defined as the following value for the Vold-Kalman Filter formulation.
        The assemble matrix : \({r^2}{{\bf{A}}^T}{\bf{A}} + {\bf{I}}\)
        2-Pole maximum diagonal value in the assemble matrix : \({({6}{r}^{2}+1)}_{ii}\)
        3-Pole maximum diagonal value in the assemble matrix : \({({20}{r}^{2}+1)}_{ii}\)
        In order to keep the effect of the additional unity value(1.0), the VK Filter Weighting Factor (r) should be limited to lower than the following maximum value. If the VK Filter Weighting Factor is greater than the maximum value, then the unity effect is lost by the numerical rounding-off error.
        2-Pole VK Weighing Factor maximum value : 4.0e+6
        3-Pole VK Weighing Factor maximum value : 2.0e+6
      • Number of Poles: It can be select the number of poles of the Vold-Kalman Filter. 2 and 3 Poles are available. Default is 2-pole option.

        Figure 7.69 Section View options

  • Slice View: It shows multiple lines. When the RPM-Frequency plot is selected, the multiple lines are determined as the Start Freq., End Freq., and Gap options. When the RPM-Order plot is selected, the multiple lines are determined as the order lines in the Plot page in the Campbell Diagram dialog.

    • Start Freq.: A frequency of the first line. This option is only enable in the RPM-Frequency.

    • End Freq.: It defines maximum frequency of multiple lines. This option is only enable in the RPM-Frequency.

    • Gap: A gap frequency of the multiple lines. The numer of lines = {(End Freq - Start Freq)/Gap + 1}. This option is only enable in the RPM-Frequency.

    • Show Section Line: It shows the multiple lines. This option is only enable in the RPM-Frequency.

    • Sectin Line Color: It can be set a color of the mulitple line. This option is only enable in the RPM-Frequency.

    • Section Curve: If this check box is checked, then the user can select some lines. And the selected lines are highright in the below plot plane.

    • Draw Overall: It shows the overall order line. The overall line is a summation of all order lines. \(\sum m\) This option is only enable in the RPM-Order.

    • Update button: It draws again the multiple lines. This option is only enable in the RPM-Frequency.

    • Zoom: It specifies the mouse operation in section view plot.Dragging in the section view plot operates as Zoom. It enables when the Select Curve is not checked.

    • Data Trace: It specifies the mouse operation in section view plot. It traces the data from the location of mouse pointer. It enables when the Select Curve is not checked.

    • Fit button: It initialize the view status such as zoom.

    • Order Line(Vold-Kalman Filter): It shows Vold-Kalman multiorder tracking filter results for the order lines.
