Abstract:

An active heated gloves method was brought forward to develop space suit assembly(SSA) gloves of astronauts who often have to come back to the vehicle for the chilled hand during an extravehicular activity(EVA). The boundary element method(BEM) was utilized to make calculation simple and to get a three dimensional temperature field easily,since it has one characteristic that the approximate calculation is only based on unknown functions on the dots of the boundary fulfilling integral calculus equations. The temperature field model of finger and EVA spacesuit glove was proved through experiment. An optimal heated scheme,which was proved by the experiment of a heated stimulant glove,was supplied to deal with the chilled hand during EVA shadowed from the sun and the earth.
