摘要
The spring suspension of an ambulance couch has three degrees of freedom. Its guide spacious mechanisms is parallelogram for vertical suspension; on the upper base of which is a double Cardan suspension with horizontal axes. The vibroisolation is realized by pneumatic springs with a position control. So that all proper frequencies might be lower than 1 Hz., it is necessary to equip the springs with additional volumes. There have been determined the conditions of the stability and the ill-effect of the position control has been proven.
