摘要
利用SolidWorks软件建立车架有限元模型,并利用ANSYS Workbench对该车架进行了模态分析。进一步分析了在柴油机激振力和路面激振力的作用下车架发生共振的可能性,为将来车架进行结构优化提供了理论依据。
The finite-element model of the frame of the heavy truck were established based on SolidWorks, and the normal model analysis was performed for the frame. The possibility of the res-onance was analysised by efforts of road surface roughness and the diesel engine exciting, and the paper provided the theory basis for the optimiza-tion of the frame.
