This paper presented an analysis of the gear shifting performances of a multipurpose vehicle transmission in driving condition by Ricardo's Gear Shift Quality Assessment (GSQA) system. The performances of the transmission included the travel and effort of the gear shift lever and synchronizing time. The mathematic models of the transmission including the gear shift mechanism and synchronizer were developed in MATLAB. The model of the gear shift mechanism was developed to analyze the travel map of the gear shift lever and the model of the synchronizer was developed to obtain the force-time curve of the synchronizer during the slipping time. The model of the synchronizer was used to investigate the relationship between the performances of the transmission and the variation of parameters during gear shifting. The mathematic models of the gear shift mechanism and the synchronizer provided a rapid design and verification method for the transmission with ring spring. © 2014 Can Yang et al. Source

This paper conducted a research to analyze the chassis of the tractor by finite element method. The four working condition of the chassis was analyzed in ANSYS and finally the stress and displacement nephogram was obtained. The research provided a way to improve the performance of the tractor chassis. © (2014) Trans Tech Publications, Switzerland. Source
