Profile Design

Systems approach in design carefully considers the following:

Vehicle Specific

Dynamic performance
Curving performance
Wheel wear rates
Feasibility
Maintainability

Rail Specific

Rail wear rates
Rolling contact fatigue
Corrugation
Noise
Feasibility
Maintainability

Evaluating how “matched” wheel/rail profiles should perform, including areas such as rolling radius difference, stability, steering, stability, contact bands, and conicity:

Ensure that the profile design results in stable wheel/rail contact.

Angle of one radius to the other is the same for wheel and rail.

Progressively Curved Wheel/Rail Profile Pair

Prevent wheel hollowing through “pummelling” the profile

Contact “Zones”

Tangent Track Profile Mapping

Optimization and data integration

Friction Management

ARM works with key partners to provide friction management review and recommendations as part of our systems approach.

Appropriate application of friction management leads to:

Extended wheel flange life
Increased train availability
Reduction in rail wear (extended rail life)
Environmental cleanliness
Savings in wheel related costs
Reduced noise, corrugation, lateral forces, and RCF

ARM is well-versed in technologies and applications, including:

Gauge Face / Wheel Flange Lubrication
Top of Rail / Wheel Tread Friction Control
The right material for the right surface – dry, FM, or lubricant
The right applicator – Trackside or train mounted
