Curve Based
In curve based method, motor is represented as an Adams force element based on a user specified Torque-Speed curve.
The motor is created through following two methods.
Select Spline
Select spline from within the model.
Enter Spline File
This method allows the entry of data of Speed and Torque via external file. The File should be in .csv (Comma Separated Values) format. Motor torque is created based on the definition of the user. A Motor Spline is created in Adams using the Torque vs. Speed Input. This Motor Spline contains the data of the input file. The Spline Torque is calculated as a function of AKIMA FITTING METHOD (AKISPL).
AKISPL (First Independent Variable, Second Independent Variable,
Spline Name, Derivative Order)
Create Data Points
This method allows direct entry of data into the table present in the motor wizard. Here X axis represents the data of Speed (RPM) and Y axis represents the data of torque. The user can visualize the plot of the entered curve points. Graphical editing is an added feature. This method also calculates spline torque as a function of AKIMA FITTING METHOD (AKISPL).
The Curve based method automatically creates Adams entities like design variables, state variables, functions, splines, Adams Curves and the torque itself. The resulting model runs in Adams Solver and the following Output requests are automatically created for the user.
1. Motor Torque
2. Motor Speed
3. Power
