Case Study

`Acoustic Treatment' to `Dynamometer Test Rig'

Process Details: Acoustic treatment to a `Dynamometer Test Rig' for a facilities management company with themaintenance franchise for a fleet of passenger trains and the `Condition Monitoring' of the associated `RailwayRolling Stock'.

Scope of Work: To design, manufacture and deliver the required equipment suitable for the end users specificrequirements.

Design Considerations: -

• The overall design & construction (bespoke to this particular testing process) being fit for purpose inproviding a safe working environment for operations & maintenance personnel - practical, cost-effective &functional, whilst reducing ambient noise levels in the surrounding area.

• The enclosure manufactured in two identical halves, for positioning either side of the train bogey and theinstalled `Dynamometer Test Rig'.

• Enclosure shaped to suit the train profile and associated rolling stock.

• Buffers and compressive seal arrangement where enclosure contacts the rolling stock, with rubber skirtingeither side and across the rail tracks.

• Free flow type ventilation with outlet vents for the exhaust gases at roof level, all attenuated to preventnoise emission.

• Heavy duty castors suitable for the total calculated load, fully swivelling and lockable. Large diameterwheels for ease of manoeuvrability / relocation within the testing depot. Wheels of a composite typematerial for durability, longevity etc.

• Castors mounted on out-riggers for maximum stability during transportation , re-positioning etc.

• Hinged personnel / emergency exit doors for ease of access / egress during the test cycle.

• Strategically positioned acoustically insulated vision panels enabling operations and maintenancepersonnel to oversee the testing process form outside the enclosed areas.

Acoustic Performance: The acoustic panels utilised in the design were rated at Rw35dB with the overallperformance dependent upon satisfactory sealing down to the track. When well sealed, the mobile enclosureshould provide an average noise reduction of 25-28dB.
