WebThe shimmy phenomenon has been treated as a non-linear problem which is solved using the method of equivalent linearization and also with the aid of an analogue computer. … 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 … foyers house iv2 https://aksendustriyel.com

As the same grinding wheel was used for this experiment, the thickness of the wheel could be ignored and L × H was taken to approximate the degree of concrete wear damage. The higher the value, the lower the abrasion resistance of the concrete.
