Abstract: With the 3 t forklift triple mast system with a maximum lifting height of 3 m as a study object,the paper an-alyzes the basic stress situation of the mast system under critical condition after learning the entire basic structure and oper-ating characteristics.According to the structure feature and size parameters of the mast system,the paper uses SolidWorks 3D software for solid modeling,seamlessly introduces into Ansys Workbench for the finite element analysis.The structure statics analysis is performed for mast system under the critical condition with the most severe stress working case,to get to-tal displacement deformation cloud atlas,equivalent stress cloud atlas for the triple mast system.With the inner mast as an example,modal analysis is performed after the pre-stress is applied to get the inner mast modal solution.The result shows that the mast deformation under critical condition,equivalent stress value,inherent frequency of first-order modal of the forklift mast system meet the requirements specified in the forklift design code,providing reference for further optimizing the mast system and preventing resonance in daily operation.
