3DSSPP
Three-Dimensional Static Strength Prediction Program
Overview
3DSSPP is a biomechanical analysis software — used to calculate the spinal compressive forces and the percentage of the working population capable of performing a specific manual handling task without exceedin g strength limits. The programme models the human body as a series of rigid links and calculates the static forces acting on the spine and joints during a defined posture and load condition — producing predictions of lumbar compressive force, shear force, and joint moments alongside population strength capability data. 3DSSPP is widely used by ergonomists and industrial engineers to evaluate and redesign manual handling tasks, workstation heights, and tool designs — providing a quantitative biomechanical ba sis for ergonomic decision -making.
