Abstract

For a clear understanding of this problem a basic knowledge of theoretical aspects is essential. An analysis of the vibrating system is therefore given, together with the effects of out-of-balance and torque harmonics.

Following a description of some forms of mounting unit, the author deals with incidental vibrations which are often caused by the flexibility of the vehicle structure. The elimination of these vibrations has been a major problem in recent years. Besides some orthodox designs described in detail, reference is made to a three-cylinder in-line, a three-cylinder opposed-piston engine mounting arrangement and the steel spring mountings used by an Italian car manufacturer.

An appendix gives the formulae for calculating the various modes of vibrations and their frequencies. A further section shows the properties of two rubber sandwich mountings arranged in V-formation.
