Analysis of dynamics and fit of diving suits

Paper presents research on dynamical behaviour and fit analysis of customised diving suits. The special diving suit above all protects the human body from hypothermia and various forms of injury, therefore, the size and cutting pattern of the diving suit should be completely adapted to the measures and shape of the diver's body [1]. Diving suits models are developed by using the 3D flattening method, which enables the construction of a garment model directly on the 3D computer body model and separation of discrete 3D surfaces as well as transformation into 2D cutting parts [2]. 3D body scanning of male and female test subjects was performed with the purpose of body measurements analysis in static and dynamic postures and processed body models were used for construction and simulation of diving suits prototypes. All necessary parameters for 3D simulation were applied on obtained cutting parts, as well as parameters values for mechanical properties of two neoprene materials [3]. Developed computer diving suits prototypes were used for stretch analysis on areas relevant for body dimensional changes according to dynamic anthropometrics. Garment pressure against the body in static and dynamic conditions was also analysed. Garments patterns for which the computer prototype verification was conducted were used for real prototype production. Real prototypes were also used for stretch and pressure analysis in static and dynamic conditions. Based on the obtained results, correlation analysis between body changes in dynamic positions and dynamic stress determined on computer and real prototypes was performed.
