  • THE ISOLATION OF VIBRATION IN THE CUSHION MECHANISM

    The present report is concerned with the isolation of vibration in the so-called cushion mechanism, that is, with the isolation of vibration when a sinusoidal excitation or a random excitation is given to the foundation of amodel with two degrees of freedom. Their relation seems to have been left unclarified as yet.
    The authors consider it necessary to make clear the relationship between the characteristics of the response to random excitation and that of the response to sinusoidal excitation, and try to compare these two cases in the above-mentioned system.
    Results obtained from them are useful for the design of rubber isolations.

    The mechanical properties of vulcanized rubber materials are well-known to be variable with such factors in processing as base polymers used, compounding. and curing. Accordingly, it is very important for designs of rubber goods to reveal the relationships mentioned above.
    In the present paper, the influences of curing systems and states upon the stress-strain behaviors under simple extension as a sort of typical mechanical properties are investigated on IR and NR vulcanizates.
    It is disclosed that the stress-strain behaviors of rubber vulcanizates are not only determined directly by the curing states, but also influenced by the type of curing systems and curing conditions. This phenomena are observed more positively on NR than on IR, but both base polymers have the same features in the relation between the mechanical behaviors and curing.
