Abstract
Forklifts are often used in close quarters, and the high load capacity and working intensity put forward high performance requirements for the fork. The structural design of the fork plays a key role in the efficiency and reliability of the forklift. In the work, the pitchfork strength of the forklift structure was studied using package modeling and finite element analysis FreeCAD. Lifting the forks with a load can cause the forks to deform, causing premature cracking and rapid growth and eventual failure. Both numerical calculations and visual analysis showed consistency, and stress concentrations were observed at the fork neck, demonstrating the accuracy of the established finite element model.
