Calculation of trial weight mass for rotor balancing
Mt = Mr × Ksupp × Kvib / (Rt × (N/100)²)
जिथे:
Mt - ट्रायल वजन वस्तुमान, ग्रॅ
Mr - rotor mass
Ksupp - समर्थन कठोरता गुणांक (1-5)
Kvib - vibration level coefficient
Rt - trial weight installation radius
N - rotor speed, rpm
Mt - ट्रायल वजन वस्तुमान, ग्रॅ
Mr - rotor mass
Ksupp - समर्थन कठोरता गुणांक (1-5)
Kvib - vibration level coefficient
Rt - trial weight installation radius

Calculator Description
This calculator is designed to calculate the trial weight mass required for the dynamic rotor balancing procedure. Proper selection of trial weight mass is critical for successful balancing.
हे कसे कार्य करते
The calculator uses an empirical formula that takes into account rotor mass, weight installation radius, rotation speed, support stiffness, and vibration level.
Support stiffness coefficient (Ksupp)
- 1.0 - अत्यंत मृदू आधार (रबर डँपर्स)
- 2.0-3.0 - माध्यम कठोरता (मानक बेअरिंग्ज)
- 4.0-5.0 - कठोर आधार (विशाल पाया)
Vibration levels and coefficients
- Low (up to 5 mm/sec) - Kvib = 0.5
- Normal (5-10 mm/sec) - Kvib = 1.0
- Elevated (10-20 mm/sec) - Kvib = 1.5
- High (20-40 mm/sec) - Kvib = 2.0
- Very high (>40 mm/sec) - Kvib = 2.5
महत्त्वाचे! The trial weight mass is selected so that its installation causes a noticeable change (>20-30 degrees) in phase and (20-30%) in vibration amplitude.
Two-plane balancing procedure
- First run (without weights) - initial vibration is measured
- Second run - trial weight is installed in the first plane
- Third run - trial weight is removed from the first plane and installed in the second plane
Critical!
- Correction weights must be installed at the same radius as trial weights!
- After each trial run, trial weights are removed!
- Correction weight is installed at the calculated angle from the trial weight position in the direction of rotor rotation!
