Project Description

Internal Vibration performance of Metro Rail coaches are an important parameter in deciding the passenger comfort, fatigue and factors of safety as well. Standardised designs of Rail Coaches incorporated into localised production tend to introduce many variables and deviations into the manufacturing process thus with a likelihood of increased vibration and noise parameters.

Benchmarking the indigenously produced Metro car coaches against reference is an involved test activity; considering many operational variables and boundary conditions, a detailed test plan was worked-out to correctly assess the vibration performance of the 2 variants of newly built coach cars.


Working cohesively with the customer engineering teams, NV Dynamics was able to conduct all the tests and produce compelling technical reports and results as per compliance documents of reference.
