Validation of MAIHAK Torque Power Meter

Validation of MAIHAK Torque Power Meter
System Overview

The following methods for the main engine power determination with Maihak Torque Validation show the possibilities of self-validation.

  • An offset algorithm informs the user if the engine-specific limit for the torque offset is exceeded during standstill. In this case, a calibration of the system is essential.
  • The dashed line shown in the figure indicates this limit for a short-term permitted offset at standstill. If this behavior remains undetected, it can lead to a mismatch of several percent.
  • In the dynamic case, the frequencies of the negative-correlating vibrating sides are monitored. If this behavior changes, the user receives a message for implausible operation.
