关于摆锤式冲击弯曲试验冲击载荷精确测定的研究
Research on accurate measurement of impact load in pendulum-type impact bending test
摘要
Abstract
A method of accurate measuring impact force based on stress wave propagation phenomena is proposed here. The measurement of load-time curve is gained by modifying the pendulum-type impact test machine. Then a relatively high accuracy impact force is obtained according to the principle of progressive integral solution,with the transfer function gained from calibration test and application of Fourier transform and inverse transform. At the same time the usefulness of this method in measuring dynamic load of both high and low strength materials is tested and verified by the examples.关键词
