1、Designation:D599296(Reapproved 2018)Standard Guide forDynamic Testing of Vulcanized Rubber and Rubber-LikeMaterials Using Vibratory Methods1This standard is issued under the fixed designation D5992;the number immediately following the designation indicates the year oforiginal adoption or,in the case
2、 of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers dynamic testing of vulcanized rubberand rubber-like(both hereinafter termed“rubb
3、er”or“elasto-meric”)materials and products,leading from the definitions ofterms used,through the basic mathematics and symbols,to themeasurement of stiffness and damping,and finally through theuse of specimen geometry and flexing method,to the measure-ment of dynamic modulus.1.2 This guide describes
4、 a variety of vibratory methods fordetermining dynamic properties,presenting them as options,not as requirements.The methods involve free resonantvibration,and forced resonant and nonresonant vibration.Inthe latter two cases the input is assumed to be sinusoidal.1.3 While the methods are primarily f
5、or the measurement ofmodulus,a material property,they may in many cases beapplied to measurements of the properties of full-scale prod-ucts.1.4 The methods described are primarily useful over therange of temperatures from 70C to+200C(100F to+400F)and for frequencies from 0.01 to 100 Hz.Not allinstru
6、ments and methods will accommodate the entire ranges.1.5 When employed for the measurement of dynamicmodulus,the methods are intended for materials having com-plex moduli in the range from 100 to 100 000 kPa(15 to15 000 psi)and damping angles from 0 to 90.Not allinstruments and methods will accommod
