Posture prediction is one of the most important aspects of virtual modeling tools: once the work point to be reached is defined, posture prediction allows simulating, through inverse kinematics, the posture the operator is most likely to assume. Aim of this work is the comparison between two virtual modeling tools characterized by a different degree of complexity of the manikin kinematics. The first tool, developed by the University of Michigan and implemented in codes such as Jack Siemens, is the 3DSSPP software (3D Static Strength Prediction Program), while the second tool, developed in FCA, is a spreadsheet created in Microsoft Excel environment, with the support of Visual Basic. Comparisons were made for the angles of trunk bending and the arm elevation, and postural assessments consistent with the ISO 11226 and UNI EN 1005/4 standards were associated to them. The proposed study provides a database of postural angles for reachability operations and shows a comparison between two virtual simulation tools: in particular, the study investigates on the strengths and the limitations of a simple and rapid tool, comparing it with the reference literature model.

Abstract

Posture prediction is one of the most important aspects of virtual modeling tools: once the work point to be reached is defined, posture prediction allows simulating, through inverse kinematics, the posture the operator is most likely to assume. Aim of this work is the comparison between two virtual modeling tools characterized by a different degree of complexity of the manikin kinematics. The first tool, developed by the University of Michigan and implemented in codes such as Jack Siemens, is the 3DSSPP software (3D Static Strength Prediction Program), while the second tool, developed in FCA, is a spreadsheet created in Microsoft Excel environment, with the support of Visual Basic. Comparisons were made for the angles of trunk bending and the arm elevation, and postural assessments consistent with the ISO 11226 and UNI EN 1005/4 standards were associated to them. The proposed study provides a database of postural angles for reachability operations and shows a comparison between two virtual simulation tools: in particular, the study investigates on the strengths and the limitations of a simple and rapid tool, comparing it with the reference literature model.
