| Abstract: | In this
paper, the differential equations of beam elements are derived out with finite element
method treating displacement function as triple B-Spline function. An example of an
elastic fourbar link mechanism is presented and the elastic dynamic analysis is practised,
the analytical results are in good agreement with experimental results. |
