Stand experiments of hunting of a bolsterless experimental truck for high-speed electric cars using a compound circular wheel profile were conducted. Experimental results were compared with theoretical results. Stand experiments were carried out with and without yaw dampers while varying the tread surface condition (dry or oily) and direction of wheel rotation (front-half vehicle experiment and rear-half vehicle experiment). Nonlinear digital simulations for these stand experiments were conducted. Simulation results agreed well with experimental results, verifying the validity of the simulation method. Then, eigenvalue analyses for three linearized models (front half of vehicle, rear half of vehicle and whole vehicle) were performed. Results of linearized analyses coincided well with experimental results, especially in the case without yaw dampers. Critical speeds of these three models were nearly equal, implying that hunting characteristics of the whole vehicle could be estimated by half-vehicle stand experiments.
