Abstract
A nonlinear curved spring has a free form shape. In this study, the
curved beam is applied a nonlinear load, the load on the spring is pointed to a certain point of the space. This curved spring can be used in an orthosis. A certain
load-deformation relation of curved spring which used in orthosis can assist the
subject wearing the orthosis to climb the stairs. The analysis of the curved spring
should be non-linear due to the applied load is a constant but its direction is point
to a certain point. The deformation is hard predicted correctly for this spring. The
purpose of this study is by using the Newton’s method with ANSYS software to
calculate the deformation of the spring. Finally, these results indicate that the Newton’s method is efficacious to find the relation between load and deformation.
