3D Computer Modeling of Sitting Working Place

Ergonomic contribution to designing and modeling of sitting working place by use of computer and computer programs have been presented in this work. Influences of modeling working places to regular posture of a man during work have been reconsidered, thus its consumption of energy and fatigue are put to the minimum. For that purpose computer program have been made which with input data on various kind of work, sex and height of a worker determine optimum ergonomic parameters during modeling of sitting working place. By computer visualisation values of angle of spine curving have been calculated, angle manipulation of arms and legs for three anthropometric heights of workers 160 cm, 175 cm and 190 cm. Dimensions of manipulative body space have been established by computerised 3D anthropometric analysis of movement as for example, reach of arms, leg, head, back etc positions. In this process dimensions of machine and working space surrounding it in respect of optimal utilisation have been put in accordance with anthropometric size of a man.
