r, thus as the basis that follow-up fatigue behaviour contrasts.Then when frequency is 30Hz, staircase method is adopted, selected forward load τ
m=0.35 τ
r, the amplitude τ of setting first sample
aif first sample does not reach set cycling condition, just τ when making next sample
areduce a tolerance value, if reach set ring condition, just the τ of next sample
aimprove a tolerance value, by that analogy.Because in elastic attachment adhesive fatigue property test, vibration number is many, need to reach 1,000,000 times, but glass surface is smooth, friction factor is little, and glass baseplate is easy to slide in vibration processes, therefore the accuracy of assay is affected, and the pressure of fixture and drawing force lower-glass frangible, use inconvenience, operability is poor, inefficiency, time-consuming, effort.
