Structural Analysis and Improvement of Large-Scale Forklift's Wheel Rim

Abstract

A large-scale forklift's wheel rim appeared cracking phenomenon in the course of use. This article summarized and analyzed force of the forklift's wheel rim according to the typical working conditions of forklift, and calculated the load of various working conditions. It provided the correct boundary conditions for the finite element analysis of the wheel rim [. After the analysis of wheel rim's three typical conditions, found the weak parts of the structure of the rim, and this part was consistent with the feedback part, so it proved correct of the finite element analysis model. Clever was used ribbed-plate and punching groove to strengthen the weak part of wheel rim and the finite element model was used to calculate and check the improved wheel rim again. The results showed that the improved wheel rim stress decreased quite, so the measure was correct.
