Summary:

This paper presents an analysis of the results of four years of theoretical and experimental work on EVA Suit Flat Pattern Soft Joints performed within the framework of the predevelopment work for the European EVA Space Suit under a ESA contract. During this project the most representative EVA Suit mobility joint breadboards have been designed and manufactured and a specific test bench has been developed and constantly perfected to perform a complete series of mobility joints tests.Flat Pattern Soft Joints are used from the glove fingers mobility joints to the waist mobility joint and the combination with bearings gives good mobility performances these performances are best adapted to the EVA (Extra Vehicular Activity) task requirements and can be used for all of the EVA suit mobility joints. The technology of the suit flat pattern mobility soft joints is, of course, a key issue of the general mobility performance.The paper is a continuation of the SAE paper series 932098 "Performance of EVA Suit Mobility Joints Influence of Driving Parameters", (23rd International Conference on Environmental Systems Colorado Springs, July, 1993) which identifies the EVA Suit mobility joints design driving parameters.All the flat pattern soft joints referenced on this paper have been designed under the European EVA Space Suit specifications and integrated into the Suit Demonstrator.The object of the paper is the analysis of the flat pattern soft joints performances according to each design driving parameter in order to give an assessment of the flat pattern soft joints behaviour and possibilities. It starts with the fiat pattern soft joints definition and joints concepts identification and follows on with the analysis of the torque performances of the flat pattern soft joints as a function of the following design driving parameters:
