ParametersDescription

Dimension (Range)

1. Simulation Type

Use to set the simulation type:

- Acceleration

- Deceleration

- User Input

N/A
2. Sampling Frequency

Use to set the sampling frequency which is set to the maximum step size as follows.

Parameters in the Assembly Manager Power Flow tab

Frequency
3. End timeUse to set the ending time. Time(s)
4. Result NameUse to set the result name and the path.N/A
5. Input Shaft SetUse to select the input Shaft Set.N/A
6. Rotating directionUse to set the rotation direction of the input Shaft Set. If CW is selected, the sign of the rotational direction is negative with respect to the Shaft Set direction. If CCW is selected, the sign of the rotational direction is positive.N/A
7. Input PowerUse to set the input power.Power (Kw)
8. RPM-Power MapUse to set the RPM-Power map. A simulation scenario can be used as the map by using this option.N/A
9. Max TorqueUse to set the maximum torqueTorque(Nm)
10. DurationUse to set the duration of the acceleration or deceleration.Time(s)
11. Start Speed(RPM)Use to set the starting rpm.Angular velocity(RPM)
12. End Speed(RPM)Use to set the ending rpm.Angular velocity(RPM)
13. Number of Interpolation dataUse to set the number of interpolated data. The input motion is created by the spline. If the input speed varies, this value is very important.N/A
14. Output Shaft SetUse to set the output Shaft Set. At least one output Shaft Set must be selected.N/A
15. Split (%)Use to set the power-ssplit percentage. The sum of percentages must be 100.Percentage(%)
16. Reduction RatioShow the final reduction ratio. If you do not define an output load, you can input a value directly and this could be used during the power flow check.N/A
17. Efficiency (%)Use to set the efficiency percentage.Percentage(%)
18. Output TorqueShow the output torque at output Shaft Set.Torque(Nm)
19. Output SpeedShow the calculated output speed.Angular velocity(RPM)
20. TransmitUse to select the gear set to engage. If a gear set is not selected, there is no gear meshing during the simulation.N/A
21. Power Flow CheckUse to calculate the power flow.N/A
22. Input motion

Show the final input motion which considers all related parameters.
