Objectives:- Understand the relationship between Design and Ergonomic Design.
- Mastering the contributions of Anthropometry and Biomechanics in Ergonomic Design (clearance, reach, posture and strength).
- Identify anthropometric measurements bi or three-dimensional, depending on the design requirements of a system.
- Mastering how anthropometric and functional characteristics of a population impose constraints on the design process.
- Know the Digital Human Models (DHM) developed under the ergonomic design.
- Mastering the use of a two-dimensional DHM in the optimization of a system.
- Using a three-dimensional DHM to evaluate the effect of forces on the human body, in terms of design proposals.
- Justify design solutions of physical systems (workspaces and layouts) using criteria of safety and comfort for potential users and system efficiency.
Contents:Intervention under Design Physical Systems:
- The practice of Ergonomic Design within multidisciplinary teams;
- Methodological approaches in the design;
- Selection of anthropometric data according to the requirements of the design problem.
The Digital Human Models (DHM) in the Design of Workspaces:
- The evolution, classification, advantages and application areas of DHM models;
- Study of WorkMan HARSIM and models developed in the laboratories of FMH Ergonomics Laboratory/ Ulisboa;
- Optimization of jobs with HARSIM model.
Designing workspaces and layouts using two-dimensional DHM:
- Domain in the development and editing of primitive two-dimensional graphics using a program for computer aided design;
- Parameterization of two-dimensional DHM;
- Optimization of layouts and workplaces, in terms of anthropometric variables (clearance, reach, posture and strength) and the requirements of the work situation, using DHM.
Evaluation:Oral presentations supported by PowerPoint, about the different topics of the program. The mastering related to computer-aided design, two-dimensional Digital Human Models and HARSIM, is developed with real examples of work done in the Laboratory of Ergonomics of FMH/Ulisboa. At the end of this course, students must defend a project (development of a physical system), associated with the contents taught in the course. It is a discipline with a strong practical component, aspect that is reflected in the evaluation model.
Continuous assessment: 50% practical component (worksheets) and final work + 50% theoretical component (final exam) with minimum of 9.5 in each component.
Final evaluation: exam (50%) and defense of a practical work (50%).
