Patent ID: 7024922

Claim:
A viscoelastic characteristic value-measuring apparatus comprising: an input bar and an output bar arranged in a straight line to hold a specimen made of a viscoelastic material therebetween, wherein said length of said input bar is set to not less than 1500 mm and not more than 2500 mm, and said length of said output bar is set to not less than 500 mm and not more than 2500 mm; first and second strain gauges installed on said input bar to measure an incident strain wave generated when a front end of said input bar is hit and a reflected strain wave; and third and fourth strain gauges installed on said output bar to measure a transmitted strain wave transmitted from said input bar to said output bar through said specimen, wherein said input bar and said output bar are made of a viscoelastic material; and a length of said input bar is set so that the reflected strain wave is damped and a re-reflected strain wave is not generated.
