| Abstract: | The deformation of the laterally-set helical spring isolator is studied,characterized by large displacement with small stain.Based on the Mottershead's linear helical rod clement and the Newton-Raphson iteration with changing local coordinates, the relations arc deduced between displacements and forces on the isolator.The result shows there exists a quadratic term on the stiffness of the main direction of the isolator,i.e.,the stiffness gets softer when compressed and stiffer when pulled.And the results are compared with those from calculation with straight beam elements and those of experiments. |
