Factors affecting the service life of tractor track shoes

1.Soil abrasive particles and medium The aggravation of wear at each wear part of tractor track shoe is closely related to the characteristics of soil abrasive particles and medium conditions. According to the measurement of energy spectrum probe, the soil is widely distributed on the wear surface, especially in...

Prospect of finite element method for tractor gearbox shell casting

The finite element analysis and topology optimization design of tractor gearbox shell casting under static conditions are carried out. The shell structure load is simple and does not consider fatigue, durability, reliability and other multi-body dynamics design requirements. Therefore, the optimization results have great limitations: only static analysis and...
