This article presents a new design of supporting tethers through the concept of force distribution. The transmitted force applied on tethers will be distributed on the new tether design area, resulting in low acoustic energy transferred to anchor boundaries and stored energy enhancement. This technique achieves an anchor quality factor of 175,000 compared to 58,000 obtained from the conventional tether design, representing a three-fold enhancement. Furthermore, the unloaded quality factor of the proposed design improved from 23,750 to 27,442, representing a 1.2-fold improvement.
本文通过力分布概念提出了一种支撑系绳的新设计。施加在系绳上的传递力将分布在新的系绳设计区域，从而降低传递到锚固边界的声能并提高储能。与传统系绳设计获得的58000相比，该技术实现的锚固品质因数为175000，提高了两倍。此外，所提出设计的空载品质因数从23750提高到27442，提高了1.2倍。
