摘要
应用投影寻踪回归技术,对非正态、非线性悬栅消能率实验数据,用1/5数据建模拟合,4/5数据留做预留检验,拟合合格率92%,预留检验合格率92%,并与激光测速得出的消能率及原型观测的消能率完全吻合。
The damping ratio data with suspension girder nonlinear were dealt with PPR technology. The 1/5m data were used to fit simulation then the others data were used to prepare for verification, the former qualified ratio is 92%, the latter qualified ratio is 92% too. Result displays that our damping ratio with suspension girder accords with the damping ratio with laser speed and prototype.
