  • Abstract:In order to solve problem that common field equipment could not adapt to field environment with varied ridge spacing and plant height,multi-functional hydraulic driven field operating platform was designed and developed,which could meet demands of field operation with varying row spacing and height,and could improve adaptability of platform.Multi-functional hydraulic driven field operating platform was driven by hydraulic drive mode,through mechanical analysis,power demand of whole machine was determined,and suitable engine,hydraulic pump,hydraulic motor and other hydraulic components were selected,power matching of operating platform was completed.Mesh generation and loads applying were applied to adjusting bracket that was a key part of multi-functional hydraulic driven field operating platform by using ANSYS Workbench simulation software,static analysis of adjusting bracket was carried out,strength and stiffness were checked,that met design requirement.Full load climbing experiment of multi-functional hydraulic driven field operating platform was carried out,results showed that power matching of whole machine was reasonable and met requirements of design and application.
