NV DYNAMICS...Your solutions partner in Noise and Vibration engineering
We are an ISO certified, UL listed, industry recognized team of core engineering professionals, with strong skillsets in approaching and solving complex real life Noise, Vibration and related engineering tasks
From our basics of test based activities, we have grown to a complete domain solution provider, combining analytical and test approach in a well-balanced ratio, NV Dynamics has become the preferred partner for our customers to work as their extended facility.
Our capabilities are based on the industry knowledge, solutions based approach, infrastructure, software tools and human resources combined with various institutional tie-up we have networked to synergize the efforts.
NV Dynamics is capable of catering to almost every need of our customer in Acoustics, Vibration and related engineering dynamics domain. Few of the services are listed below
Noise & Vibration Measurements, Analysis and Mitigation
Complete profile of instrumentation, analysis tools and engineering resources to take up most of Noise and Vibration activities across process, manufacturing, automotive, R&D, Civil Structural and other verticals. One of investigations, root cause analysis and mitigation are some of our core strengths.
Using the industry standard LMS Modal test and analysis systems, we cater from impact based modal to multi-shaker based testing combined with Modal based modifications & Modal Updating.
Order Tracking & Rotating Equipment Analysis
Variable speed rotating equipment, gear box and multi-stage drives, most require high quality adaptive sampling techniques for vibration analysis; with refined and improved instrumentation with powerful software tools, we provide comprehensive test solutions for most of rotating equipment analysis.
Room & Building Acoustics
Acoustically treating buildings, inside out – working both at design stage and at a post construction scenario with methods and implementation plans that are standardised by practice. We use Sound Plan and other professional assessment and modelling tools to achieve prescribed acoustic parameters on case to case basis
Product Noise performance, Noise design, source localisation all require good quality real time octave analysis ; using high quality sets of microphones, multi-channel real time analysers and in compliance to many international standards, NV Dynamics conducts octave test and analysis as a qualified activity.
The biggest known source of high vibration in most of the rotating equipment; however, the correct understanding of unbalance quantities, system sensitivity and correction methods have made our practices far ahead of competition; 1, 2 and multiplane balancing activities are conducted on a regular basis at our customer sites achieving values down to G1 grade as per ISO 1940
Metro Rail, Ground, Civil Structural & Building Vibration Analysis
We are the specialist team with over 400 tasks of ground and building vibration assessments to our credit till date; from Metro Rail Via-ducts to Underground Tunnels, from Water canals to high rise buildings, we have worked on many critical projects & assignments both in India and outside; special instrumentation, both local and remote data monitoring tools combined with compliance to test procedures, we have the right combinations of expertise to handle any of ground and civil structural vibration issues.
Noise & Vibration control
Turn-key start to end solution approach to most of the NVH engineering consulting tasks have put us into the position of delivering mitigation plans both for Noise & Vibration issues; The CONTROL approach is a mix of both passive and active implementation of solutions that may be focussed around the source, path or the destination. We have aligned with some of the best brands of products from around the world to deliver right solutions on case basis.
Identifying the source of noise, segregating frequencies of specific interest, ranking them as per the design and operational use requirements, qualifying the source by its acoustic power for absolute determination of noise values are all a part of Noise investigation; using G.R.A.S Probes, associated Sound Intensity Instrumentation and software tools, NV Dynamics has worked on a variety of Noise investigation projects covering multi-engineering applications.
Condition Monitoring Services
Bearing and rotating equipment health, assessed correctly and periodically using vibration analysis tools is one of the most proven methods to predict the bearing life; using improved trending methods, kurtosis and envelope detection techniques, we offer a comprehensive package of Condition Monitoring activity; currently we use sub-sampling methods and wireless sensors with cloud based data access and control.
All that we practice is what we preach!! Our training programs are our gateway to reach the customer with updates on current activities and updates in the NVH Domain; from fundamentals of Noise and Vibration to advanced courses on NVH subjects, we conduct regular training programs. Certifications courses are the next things we bring into the stream which enables our customer to get the credentials of certified vibration engineer.
