Wobble or shimmy begins when some otherwise minor irregularity accelerates the wheel to one side. The irregularity may be a wheel which is out-of-round, out-of-true, or out-of-balance. As the wheel rotates, it will exert a cyclic load to the vehicle frame, which if matched with the system's (vehicle and attached accessories) resonant frequency, can produce a speed wobble. During the wheel rotation, a restoring force is applied in phase with the progress of the irregularity, and the … WebMar 24, 2024 · Hans got his doctoral degree, cum laude, in 1966 on the thesis entitled ‘The wheel shimmy phenomenon, a theoretical and experimental investigation with particular reference to the non-linear problem’, with Professors de Pater and van Eldik Thieme as advisers.
