| Abstract: | In this paper,the geometric model of agricultural vehicle frame is meshed by shell element based on software Hypermesh and then finite element model of frame is built.According to bearing behaviors and running conditions of the agricultural vehicle,the dynamics simulation of frame is implemented.Through the modal simulation,the natural frequency and inherent vibrational mode get.And these simulation dates provide basis for the improved design of frame structure.As a result,this paper can attain relatively h... |
