The invention discloses a supporting spherical hinge torsional rigidity nonlinear design method and a supporting spherical hinge, the supporting spherical hinge torsional rigidity nonlinear design method comprises the steps that a first limiting structure is arranged on an outer sleeve, a second limiting structure is arranged on a hollow mandrel, and a gap L is reserved between the first limiting structure and the second limiting structure in the circumferential direction; when torsion occurs, the annular rubber deforms under the action of external force, so that the outer sleeve and the hollow core shaft rotate relatively in the circumferential direction, the gap L becomes smaller, the first limiting structure and the second limiting structure rotate relatively in the circumferential direction along with the outer sleeve and the hollow core shaft, and when the gap is eliminated, the first limiting structure and the second limiting structure make contact to form a circumferential limiting structure. And the nonlinear change of the torsional rigidity is realized. The supporting spherical hinge designed through the method can generate normal torsional deformation in the early stage, after the supporting spherical hinge is twisted by a certain angle, torsional limiting is conducted, and nonlinearity of torsional rigidity is achieved.
本发明公开了一种支撑球铰扭转刚度非线性设计方法及支撑球铰,其中支撑球铰扭转刚度非线性设计方法是在所述外套上设置有限位结构一,在所述空心芯轴上设置有限位结构二,所述限位结构一和限位结构二在周向上留有间隙L;当发生扭转时,环形橡胶受到外力作用下发生变形,使得外套与空心芯轴之间相对周向转动,间隙L变小,所述限位结构一和限位结构二随之相对周向转动,当转动至间隙消除时,限位结构一和限位结构二相接触形成周向限位结构,实现扭转刚度的非线性化变化。利用本发明的方法设计出来的支撑球铰能在前期产生正常的扭转变形,当扭转一定角度后,进行扭转限位,实现了扭转刚度的非线性。
