NSV strives to maximize the performance of machinery and equipment, provide optimal environmental conditions, and minimize generated noise and vibration to reduce the impact on surrounding areas and potential complaint zones, ultimately creating a more comfortable and stable environment.
Vibration Impact Assessment
NSV conducts quantitative vibration evaluations from the architectural design stage to assess potential vibrations generated during equipment operation.
We also perform systematic vibration impact assessments based on relevant standards.
In addition, using the evaluation results and vibration transmission path analysis, we provide optimized vibration-control solutions tailored to the site environment.
Process Steps
SCROLL
Review of Received Data & Analysis of Assessment Points
We review drawings and equipment specifications to identify key locations where vibration impact is expected.
Vibration Source Analysis
We analyze major vibration-generating factors such as equipment type, operating conditions, and rotational speed, and identify the transmission paths through the structure.
Development of Vibration Prediction Model
We build a vibration analysis model that reflects the stiffness and damping characteristics of the building structure.
Vibration Simulation Analysis
We simulate vibration transmission characteristics based on actual operating conditions and predict indoor vibration levels.
Result Derivation
We quantify the simulation results to determine vibration levels at each assessment point and evaluate their impact relative to the applicable criteria.
Vibration Impact Assessment [Comparison with Relevant Standards]
We evaluate applicable vibration criteria based on the intended use of the space.
Mitigation Planning
If the results fall within the acceptable criteria, we provide recommendations for maintenance and performance stabilization.
Root Cause Analysis
If the evaluation results exceed the criteria, we analyze vibration transmission paths and key influencing factors to identify the problematic areas.
Vibration Isolation Design & Application
Based on the analysis results, we apply vibration isolation design or structural reinforcement measures and verify the improvement through re-simulation.
Noise Impact Assessment
NSV conducts comprehensive analyses of various noise sources to quantitatively assess complex noise conditions.
Additionally, based on the evaluation results and noise transmission path analysis, we provide noise-control solutions optimized for the site environment.
