Methods for model error analysis of pulse impulse measuring torsion system

摘要

Torsion system is a typical pulse impulse measuring method. Currently used analysis model is the impulse moment interaction model. According to the response characteristic analysis of torsion system under pulsed impulse action, using analytical methods, this thesis proposes error analysis methods for impulse momentary action model and also proposes the main factors of model error is damping ratio of torsion system, the ratio of pulse time as well as system impulse period. The proposed model error analysis methods facilitate pulse impulse error analysis, which provides analysis and design methods for impulse pulse measurement and error analysis in engineering.
