This study considers the effects of several parameters on the force/moment systems produced by T-loop retraction springs. The springs are studied by using the finite element method and by experimentally measuring the forces and moments from the various designs. The results show that varying the spring height can produce larger moment to force ratios as the height increases. Changes in the preactivation bends result in unsymmetric moment characteristics and also produce large intrusive/extrusive forces. The addition of helices at the bends did little to alter the springs' mechanical characteristics.
本研究考虑了几个参数对T形圈回拉弹簧产生的力/力矩系统的影响。通过有限元方法以及通过实验测量各种设计产生的力和力矩来研究这些弹簧。结果表明，随着弹簧高度增加，改变弹簧高度可产生更大的力矩与力之比。预激活弯曲的变化会导致不对称的力矩特性，并且还会产生较大的侵入/挤出力。在弯曲处添加螺旋对改变弹簧的机械特性作用不大。
