In view of tilting detection of gear hub and gear sleeves in automobile gearbox synchronizer assembly detection

there are many problems such as low degree of automation

too many uncontrollable factors and so on

the method of soft measurement is applied

taking the influence factors of the amount of tilting as independent variables

based on theoretical analysis and experimental test and under the tooth side centering mode

a soft measurement model of synchronizer gear hub and gear sleeves is built.According to the sample data collected in the field

depending on the predict amount of tilting and detection amount of tilting

put quantity into MATLAB to make simulation analysis.The simulation results show that the actual situation of model of the soft measurement can reflect the amount of tilting

the relative error of the mean value is less than 1.1%

which can meet the production demand of the company.
