    Output from a curvature analysis

    How do you export the data from a curvature analysis (ie into excel) or even save the graphical output as an image?

    PWM motor controller interfers with strain gauges

    Motor: 24 V DC, 6 A PWM: 15 A, 17 kHz (measured approximately from ocilliscope) The stain gauges are attached to a metal support which is mounted on a metal tube, which houses the motor. The gauges are insulated from the support. The motor controller and strain gauge amplifier have separate...

    PWM motor controller interfers with strain gauges

    Test apparatus includes a DC permanent magnet motor and strain gauges. The speed of the motor is controlled from a PC through a pulsed width modulation controller board. When this motor is running at anything other than full speed, there is a large offset in the amplified strain gauge output (up...

    Defining Double Curvature Using Catia

    I am trying to develop a method of classification for tooling complexity through the extent of double curvature of a surface. Whilst the Curvature Analysis provides a suitable graphical output for an individual curve the output from the Surface Curvature Analysis appears limited in a max and min...

    Use of Ln in a formula

    I have checked the settings and they are all similar. The formula I am trying to use is - Ln((length(`Geometrical Set.1\Line.30`)+length(`Geometrical Set.1\Multi Output.17 (Project)\Project.30`)) /60 ) but still giving the error as before even placing "in" after each length.

    Use of Ln in a formula

    I am trying to use the natural log function in a model to calculate a length, however I keep receiving the following alert- "Units are not homogeneous (m into Constant). We advise you to specify precise units for constants, otherwise the International System Units will be the default...
