Aim of the work was the design of instrumented trackbars to be mounted on rotating tracks of modern groomers for strain data acquisition in normal snow field operations: the knowledge of field load spectra and material fatigue properties allows for lightweight trackbars development. A rugged and compact acquisition system was adopted and applied to the trackbars in a protective case. Two trackbars were strain gauged with ten strain channels each, applied at two significant structural sections in correspondence of the support wheel and of the traction wheel, in order to measure the bending actions in two planes. Load acquisitions were performed to record the strain spectra for significant severe events and for typical use and compared with fatigue test data from a fatigue test bench developed at the company.

Abstract

Aim of the work was the design of instrumented trackbars to be mounted on rotating tracks of modern groomers for strain data acquisition in normal snow field operations: the knowledge of field load spectra and material fatigue properties allows for lightweight trackbars development. A rugged and compact acquisition system was adopted and applied to the trackbars in a protective case. Two trackbars were strain gauged with ten strain channels each, applied at two significant structural sections in correspondence of the support wheel and of the traction wheel, in order to measure the bending actions in two planes. Load acquisitions were performed to record the strain spectra for significant severe events and for typical use and compared with fatigue test data from a fatigue test bench developed at the company.
