抄録

The large deflections of a circular-arc cantilever spring of trapezoidal profile subjected to a concentrated force at the free end in the lateral direction have been studied. A solution of the nonlinear beam equation is obtained in the form of power series. However, the power series used yields poor convergency as the shape of spring approaches the triangular profile and it diverges lastly. An approximate solution is also derived from the nonlinear beam equation after approximated appropriately. In comparison between results calculated from the seriesform and approximate solutions respectively, it has been seen that the approximate one gives practically satisfactory results. Numerical results due to both the series-form and approximate solution are also presented.
