A global provider of HVAC systems chose Sound Answers to provide test service support and perform vibration validation tests on their blower motors. Both operating and stationary vibration measurements were made at the customer’s US facility. Vibration levels at various customer identified locations were made to identify resonant conditions and compared to acceptance criteria. Imbalance, steady state, and torsional vibration validation was performed along with identifying resonances of the system. This test service support allowed the customer to relieve their overburdened staff from excessive work hours during the validation cycles while maintaining quality validation testing.
