A Vibration Analysis of Flexible Shafts for Speedometers

The fluctuation of the speedometer pointer and noise froa the speedometer cable has been an ever-present problem. The cable route through the engine compartment, with its many parts, is complicated and the necessity for silence is required for today's passenger cars.

The resultant cause of meter pointer fluctuation and cable noise are discussed in this report through the use of the static characteristics and vibration analysis of the flexible shaft.

Finally, technical measures to prevent the pointer fluctuation and the cable noise are shown.
