Abstract: Different series of corrugated sleeves are designed and
produced and the working characteristics are tested. Based on the ring
shell theory, plastic theory, corrugated sleeve’s math mechanics model
is proposed, the theoretical working characteristics are calculated and
numerical simulation is proceeded through ANSYS. Both of theory result
and simulation result are consistent with the experiment result. The
research of theory and experiment reveals the quantitative working
characteristics of corrugated sleeve and the influencing rule of the
geometric parameters. When the maximal diameter doesn’t change, the
slope of elastic curve and press of the plastic yielding point increase
gradually as radius of corrugation part is increasing. When the radius
of corrugation part doesn’t change, the slope of elastic curve and press
of the plastic yielding point reduce gradually as maximal diameter is
increasing. The research founds an important basis to establish the
design method and spur similar products to be applied in engineering
practice on a large scale.
