The Optimal Design On Front Frame And Back Frame For Mine-used Forklift

Mine-used forklift is Mine-used machinery equipment, which hinged by front frame and back frame, and set loading, carriage and uninstalling together, and its motivation provided by rechargeable batteries.In view of the complexity of the underground road, we need to check the mechanical properties of front frame and back frame, at the same time, according to the results, I conduct some necessary optimization. The mechanical properties mainly consider the stress, deformation and strain of the structure whether meet the safety performance of the material, and the dangerous areas are optimized until they meet the safety performance of the material.According to general ideas of this project, I have done the following research content for CLX3rubber-type mine-used forklift:First of all, establishing forklift virtual prototype. Combined with original structure size of the forklift, I establish solid modeling of the original state using CAD design software Pro/Engineer5.0, and simplify the model properly. And then I import the virtual prototype into simulation analysis software ADAMS, add tires, road surface and the necessary constraint, complete the establishment of the virtual prototype.Next, drawing power parameters of forklift by the dynamic simulation analysis. Combining with coal mine underground working road, I have carried on overall dynamic simulation and analysis to this forklift under seven kinds of road conditions (flat and no-loaded road, flat and full-loaded road, triangle convex platform road, rectangular pit road, hemi-lateral pan road,10°climbing road, turning road), drawn power parameters, such as starting torque, stable torque, force of every joint, turning radius etc.Finally, carrying on the finite element analysis to front frame and back frame of forklift. Arranging the dynamic parameters, and according to the data, the stress, deformation and strain of front frame and back frame of forklift are analyzed using the Pro/Engineer5.0, and finding out the danger zone and optimizing them, at the same time, analyzing the stress, deformation and strain of the optimized front frame and back frame of forklift and whether they meet the safety performance of the material.This study provides theoretical basis for Virtual mechanical system dynamics simulation and optimization design of the forklift, we can improve the precision of parts design and work efficiency of the forklift by referencing this research thought, and reduce energy consumption. At the same time, the virtual prototype simulation analysis methods introduced in this topic can make up some defects, such as the long cycle and the high cost for the traditional mechanical physical system design, test and modify.
