Abstract
A flexible element of (dual) wave crest concave, it consists of a single or multiple flexible elements, in which the contour of each flexible element is composed of segmental arcs of lower wave trough (Radius=R.sub.1), (dual) wave crest (Radius=R.sub.2) (where R.sub.1 =R.sub.2) and upper wave trough (Radius=R.sub.3, R.sub.3 =R.sub.1 or R.sub.3 .noteq.R.sub.1) tangential to each other smoothly. This kind of flexible element distributes stresses and strains uniformly, increases flexibility and can bear greater angular deflection. It can be used as element for sensor, sealing, shock absorber, compensator or expansion joint, being widely applied in the field of automatic control and instrument.
