Study On The Static And Dynamic Characteristics Of The Three Stage Door Frame System Of Forklift Truck

In a 3T, maximum lifting height of 3M forklift three door frame system as the research object, in a comprehensive understanding of the basic structure and operating characteristics, analysis of the force level three door frame system under critical condition. Then according to the three gate frame system structure and size parameters, 3D modeling by SolidWorks platform, seamless into ANSYS finite element analysis software workbench. Selected triple portal frame system in critical condition, can the normal operation of the working condition for the static analysis, obtained within, and the door frame model of the total displacement deformation nephogram and stress nephogram. The modal analysis of three forklift gantry model in ANSYS workbench platform,the analysis result. The results show that the forklift triple portal frame system under the critical condition of the door frame deformation, the natural frequency of the equivalent stress values and the first-order modal meet forklift design specification requirements, resonance phenomena and provides a reference basis for avoiding further portal frame system optimization and daily operation.Then through the interface between Solid Works and Adams, seamless will forklift triple portal frame model is imported into ADAMS software, set a good working environment, according to the actual forklift triple portal frame,applied loads and restraints and drive successfully created three door frame virtual machine model. After setting the simulation time and the number of steps, the triple portal frame model to carry on the simulation computation,output measurement curve, respectively, to obtain the forklift portal frame work of travel and components under the force curves. Finally, on the output curves do in-depth analysis and reasoning, for future triple portal frame system of research, production, improvement and optimization, providing some reference.
