Mechanical sensor used to measure average or instantaneous translational power
The block represents a sensor that you can use to measure the translational power change due to one or more driveline components connected between ports R and C. The power output can be an instantaneous or average value. Two averaging options are available: period and vibration averaging.
The instantaneous power is the product of the current velocity and force. Use the instantaneous power to analyze peak power transmission and identify heavily-loaded components.
The time-averaged power is the integral of the instantaneous power over one sample period, divided by that period. For simulation times smaller than the sample period, the average power is zero. The power is constant for each sample period.
The vibration-averaged power is the integral of the power over one vibration period, divided by that period. The vibration period is the time between two consecutive crossings from negative to positive velocity values. Use this averaging method only for oscillations with velocity passing through zero. The averaging period can change if the vibration has a variable frequency. For simulation times smaller than the vibration period, the average power is zero. The power output is constant for each vibration period.
Select either instantaneous or average power measurement. The
default type is
Instantaneous power —
Output the power measured for the current time step.
Average power over a specified period—
Output the power averaged over a fixed time period.
Enter the time period used to compute the average power. Typical values include the cycle length of a reciprocating device or the actuation force.
The default value is
1. The default unit
Average power over a vibration—
Output the power averaged over one vibration period.
Enter the maximum vibration frequency over which the power should be averaged. Very high values can reduce simulation speed. Very low values can result in lower power measurements.
The default value is
1000. The default unit
