Embodiment Construction
[0073] The present invention will be further described below in conjunction with drawings and embodiments.
[0074] The symbols ''' in the present invention all represent the first-order derivative of the variable to the parameter coordinate u of the canonical central curve, and the symbols '‥' all represent the second-order derivative of the variable to time.
[0075] Embodiments of the present invention are as follows:
[0076] 1) Construct a generalized coordinate g, which is represented by the following triples:
[0077] g={q,η,r}
[0078] 2) Establish an elastic potential energy model using the following formula for the rectangular strip-shaped developable surface S, and calculate the internal stress in the rectangular strip-shaped developable surface S through the elastic potential energy model:
[0079] V = Σ a = 0 ∞ w ...
