The normal single head MiniProf Wheel instrument is extended to a TwinHead Wheel with a fixed beam between two heads. The system is magnetically attached to both wheels on the axle.
The TwinHead is efficient to obtain maximum accuracy when joint profiles are measured without moving the instrument.
The system is ideal for interaction studies between wheels and rails. Applications for a TwinHead are: Contact studies, Optimisation of wheel-rail contact, Steering/curve negotiation. Plug-in for calculating Equivalent Conicity is available.
