Snowmobile model for ride dynamic analysis

Snowmobiling involves exposure to high magnitude vibrations. Ride comfort thus forms a major design requirement, currently met through iterative prototyping and field–testing. This study thus aims at developing a snowmobile ride model. The nine degrees–of–freedom ADAMS model includes sub–models for: detailed suspension, track, trail profile, deformable ground, quasi–steady traction, and simplified rider and seat. Four trail roughnesses were characterised through Power Spectral Density. Field tests provided vehicle response. Simulations' agreement ranged from poor to good. A parametric analysis pointed to ride comfort improvements reaching 58%, based on the rms vertical acceleration at the seat.
