Key points for upgrading the adaptation technology of electric dynamometer and torque flange

1. Mechanical connection strengthening solution

• l New laser alignment process requirements: Use API XD Laser system to achieve dynamic concentricity detection (≤0.03mm/m)
• l Selection criteria for elastic couplings: Supplementary selection guide for "metal diaphragm type (speed > 10krpm)" and "rubber buffer type (impact load)"

2. Signal transmission technology iteration

• l Increase anti-interference measures: Use double-layer shielded wire (inner copper mesh + outer aluminum foil) combined with EMI filter to compress signal fluctuations to ±0.03%FS
• l Protocol compatibility extension: support configuration parameters of Profinet RT/IRT protocol (delay < 100μs)

3. Dynamic calibration system construction

• l Introduction of online calibration technology: realizing automatic zero point calibration every 72 hours using HBM T12 calibrator
• l Temperature compensation formula:

                  ΔT=α·(θ-25)² + β·(θ-25)

                  Of which, α=0.0032/℃², β=0.015/℃ (measured data of a certain type of flange)

4. Industry customized parameters

• l New energy field: Add insulation resistance requirements for 800V high voltage testing (≥100MΩ@1500VDC)
• l Aerospace: Supplement the torque attenuation compensation coefficient of titanium alloy flange (TC4 material) at low temperature -55°C

5. Maintenance strategy upgrade

• l Intelligent preload monitoring: BoltSafe wireless sensor monitors bolt stress changes in real time
• l Vibration database comparison: Establish a typical fault spectrum library (including 12 modes such as imbalance/misalignment/looseness)
