Having tested 5 excellent players by using a sail waving simulator,the author revealed the following findings: As the sail waving time increased,the physical strength of the excellent players would dwindle,but the main indexes for sail waving were reduced gradually,and sail waving became more and more unstable.

The aerodynamic performance analyses of windsurfing pumping based on dynamic mesh

Through a comparison of the similarity between bird flapping and windsurfing in structure,process of movement,compoments of the aerodynamic lift and environment,the mechanism of windsurfing pumping based on the principle of flapping flight is addressed.

First, this paper discusses the characteristic of sailing sport, especially the action characteristic of sailboard pumping and build the multi-body dynamics prototype of athlete-sport-environment according to them and gets all kinds .

The experimental rolling simulation stand for anti -rolling tank performance is a testing facility of simulating ship rolling move ment in the action of waves based on similarity rules.
