NV Dynamics was hired by Saint-Gobain Research India (SGRI) to perform ASTC assessments on three partition walls having four rooms at their facility in IIT Madras Research Park. The assessments were made by generating pink noise through a sound source to build a reverberant sound field in the source room. Noise levels were measured at multiple locations as per the guidelines of the ASTM E-336 standard within the source and receiver room. Numerical calculations were carried out to obtain the transmission loss values and using the curve fitting method, appropriate ASTC values were assigned to the partition walls.

NV dynamics was engaged by Bhilai Steel Plant to conduct vibration analysis and in-situ balancing on 4 motor drive units. Vibration assessments were conducted to check the presence of unbalance and other potential issues such as misalignment, looseness etc. Based on the vibration results, in-situ balancing was performed on the drive units which were found to exceed the acceptable limits specified by ISO 20816.

NV Dynamics was retained by Shankaranarayana Constructions Private Limited to evaluate the vibration impact, generated by the ongoing metro construction activities, on the surrounding sensitive receptors in Bengaluru. Seismic-grade accelerometers and transducers were strategically deployed at pre-determined monitoring points to capture real-time vibrational data. The collected data were later processed and compared to established industry standards for vibration severity.

NV Dynamics was contracted by International Power Corporation Pvt Ltd to conduct vibration analysis and on-site balancing for Hydro Turbine-Generator. The assessment was conducted at the operational speed of 500 RPM on both DE and NDE side of the hydro turbine-generator bearing housing. The recorded data is processed and the vibration velocity values are evaluated against ISO 20816 for severity assessments. Balancing trials were initiated to address the unbalance.
