A kind of short rock bar viscosity coefficient test method for propagating analysis based on viscoelasticity wave

The present invention relates to a kind of short rock bar viscosity coefficient test methods that analysis is propagated based on viscoelasticity wave, comprising the following steps: establishes the governing equation of rock bar viscoelasticity constitutive equation and the propagation of one-dimensional viscoelasticity wave；Governing equation, transflector theory and the viscoelasticity defect theory propagated based on one-dimensional viscoelasticity wave design one-dimensional viscoelasticity stress wave analysis program；Impact test is simulated using one-dimensional viscoelasticity stress wave analysis program, input load wave is simultaneously compared the strain wave that impact test obtains is simulated with verifying wave, keep the strain waveform of simulation consistent with verifying waveform by adjusting parameter, and then obtains the viscosity coefficient of rock bar.The present invention is more reasonable by the viscosity coefficient that the method for the continuous trial and error of simulation test obtains；Only a complete waveform need to be measured in dynamic impact test as Loaded contact analysis, another verifying waveform should not Seeking Truth be no superposition and completely, can shorten the length of rock bar in testing, be conducive to the test of natural rock viscosity coefficient.
