Helical springsTorsion problemTheory of elasticityAn exact analytical solution for the torsion problem of an incomplete torus with a particular form of non-circular cross-section has been found. The solution extends for the close-coiled helical spring the known solution of the torsion problems for ...
This study concerns the theoretical calculation of the characteristics of helical springs used, particularly, for the primary and secondary suspensions of railway vehicles: the static characteristics will be determined by an exact method where as the dynamic characteristics will be determined with the ...
The pseudospectral method is applied to the static analysis of helical springs of arbitrary shape. The displacements and the rotations are approximated by series expansions of Chebyshev polynomials. The entire domain is considered as a single element and the governing equations are collocated to yield ...

is any spring formed into a helical coils shape. Coil springs are used in compression, tension, torsion. The term coil spring in generaly used to describe a spring commonly used in automiblies used to absorb load and deflection variqations fron the vehical suspension. The AUtomotive type coil...
INSULATING SWITCHING ROD WITH A CONTACT PRESSURE ARRANGEMENT COMPRISING A PLURALITY OF HELICAL COMPRESSION SPRINGS WOUND IN OPPOSITE SENSES With regard to an insulating switching rod for initiating a drive movement into a moving contact of an electrical contact system of a switching device, and for pr...
We investigated the torsional deformation of the proposed soft actuator with respect to various design parameters, including the twist direction, diameter and helical pitch of the SMA wire, and the thickness and length of the actuator. The actuation performances of the torsional soft morphing actuator...
Helical springs connected it to the motorcycle frame, providing a restoring torque that produced the steering torque feedback. The vehi- cle's standard steering damper was present, creating a damping effect. A load cell measured the steering torque applied by the rider.5 The stiffness of the ...
