“…Besides, the model of the spiral spring could also be built through a finite element software like ANSYS, and vibration modes of the spring are directly obtained by applying loads. 15,16 One of the superiorities for these modeling methods is to reveal vibration modes of the spiral spring precisely, but they pay close attention to mechanical properties and it is hard to combine with the motor to study the electromechanical property and is also unable to eliminate the influence of the spring's mechanical vibration on the system.…”

The operational performance of the spiral spring energy storage system is affected by the vibration of the spiral spring and the electrical loss of the permanent magnet synchronous motor. It is important to eliminate vibration and reduce electrical loss. A unified control scenario for speed regulation and vibration suppression based on the minimum electrical loss is proposed. First, the spiral spring is equivalent to an Euler–Bernoulli beam and its dynamic model suitable for control is established via the Lagrange equation. Then, the unified control scenario is proposed through nonlinear backstepping control. The speed controller and current controller including modal vibration suppression and minimum electrical loss operation of the system are established, and the stability of the controller is theoretically proved. Moreover, for unknown vibration mode of the spiral spring, a vibration mode–based estimation method with the least-squares algorithm is designed. Aiming at the uncertainty of the permanent magnet synchronous motor’s iron loss resistance, an estimation algorithm based on an adaptive neural fuzzy inference system is designed. The experimental results verify the correctness and effectiveness of the proposed control scheme. In comparison with traditional backstepping control, the proposed control method can effectively suppress the vibration of the spiral spring and realize the stable and highly efficient energy storage operation of the system.

A new type of rhombic grid hyperboloid-latticed shell (RGHLS) being investigated in this study is only formed by major and secondary inclined columns without any circumferential hoop members. This intends to achieve more transparency for architectural effect by neglecting its circumferential hoop members and lateral braces in radial direction of the RGHLS, and meanwhile, the RGHLS is expected to experience a significant strength reduction. This paper numerically investigates the load resistance and hysteretic response of such RGHLS subjected to combined vertical and horizontal loads by adopting finite element method, where multicolumn interaction instability failure mechanism and load-carrying capacity of the RGHLS are being focused on. It was found that the RGHLS failed by multicolumn interactive instability between the major and secondary columns, with associated in-plane and out-of-plane flexural deformations of the columns. The overall interactive load-carrying capacity design curve N/Nu-M/Mu of the RGHLS was proposed based on numerous finite element results. The results indicate that the strength design of the RGHLS with a door opening being adopted in the practical engineering application is reliable and rational with a certain amount of safety margin. At last, hysteretic response of the RGHLS is investigated according to the loading protocol specified in AISC341-05.
