Study on Lateral Stiffness for Flexicoil Circle Springs with Rubber Pads
In order to accurately obtain lateral stiffness of flexicoil circle spring with rubber pads, based on shear shape coefficient of solid and hollow thin-wall circle section, the shear shape coefficient of hollow circle section with different ratios between inner and outer diameter was obtained by difference method. By means of curve’s differential equations of elastic straight bar with uniform section, relations between forces and displacements as well as moments and rotation angles on end surfaces of spring and rubber pads was set up. According to the principle that force and moment under the connection surface between spring and rubber pad are the same and their signs are opposite, lateral stiffness of flexicoil circle spring with rubber pads was obtained. Calculation results show that in order to obtain accurate solution, correction factor of stiffness matrix must be considered when only lateral stiffness of spring is calculated, but the correction factor can not be considered when lateral stiffness of spring with rubber pads is calculated.
