This paper discusses the stability analysis of a product while it is being handled by a forklift or pallet jack. The stability criterion is defined as the product not tipping over during relocation. There are several parameters affecting the stability of the product including its weight, width, depth and location of the center of gravity. When the product is handled by a forklift or pallet jack it is bolted onto a pallet. In this situation, the pallet width, height, bottom deck strength and friction coefficient between the forklift fork and the pallet influence the stability. Additionally, the forklift’s speed, turning radius, and deceleration all affect the stability of the product. Finite element modeling is an analytical method that can be used to evaluate the dynamic stability of a product during manual or mechanical handling. Specifically, an explicit finite element model will be solved which allows for the highly nonlinear transient dynamics that are found in complex, real world problems. This analysis method will allow the observation of the initial product dynamics, the fracture of the pallet bottom deck and then the subsequent tip-over interactions of all the bodies. This explicit method will allow the consideration of all the previously stated variables in a dynamic simulation, not possible with simple static, implicit models. The objective of the finite element modeling is to evaluate all the parameters and to provide guidelines on the maximum speed.
