Abstract-This paper focuses on the shimmy vibrations of wheeled casters. First, a new test caster is developed to freely change its mechanical properties. The accelerations of the caster are carefully measured by changing both the running velocity and the mechanical properties. Next, the running model of the caster is formulated on a horizontal plane, and the computer simulations are conducted based on the model. Then the acceleration data of the developed test caster are compared to those of the modeled caster in the computer, and it is confirmed that the simulation results have good agreements with the experimental results. Finally, some differences are discussed between the actual and computational data.
