For the characteristic curve option component, the area of opening or scaled coefficient must be specified as a function of the signal. The four columns in the data correspond to order (Signal - Spool PA - Spool TA - Spool PT) specified in the form of a table. The following parameters allows users to specify the necessary data for this calculation.
Data Source: This parameter allows users to specify the nature of the source file for the Signal (ranging from -1 to 1) vs. valve opening table. The available options are file, attachment, and inline.
file: Use this option to specify a source file (an Excel or a CSV file) located on the hard drive.
attachment: Use this option to specify a data file (an Excel or a CSV file) that is attached to the MapleSim model. To be used as an attachment, data files must be attached to the MapleSim model and be categorized under Data Sets. The attached files in a MapleSim model can be viewed in the Attachments pane under the Data Sets section. For more information, see Attaching a File to a Model. Select the desired attachment as the or parameter.
Note: If the file option is used, subsequent changes to the source file will be incorporated into MapleSim simulations.
If the attachment option is used, subsequent changes to the source file will not affect the version attached to the MapleSim model. To ensure updates to the source files are incorporated in the simulation, the file must be reattached.
inline: Use this option to directly specify the pressure vs. area relationship in the form of a table. In the or parameter the first column must contain values of the spool signal ranging from -1 to 1 and the second column must contain corresponding values of the area or scaled area.
Note: To change the dimensions of table, right-click (Control-click for Mac®) the parameter field and select Edit Matrix Dimensions. In the Matrix Dimensions dialog, enter values for the number or rows and columns and then click OK.
Smoothness: The smoothness option specifies how the data table is interpolated.
