Abstract:

To build the equivalent relationship of the mechanical behavior of ring nets under static punching and dynamic impact conditions, a series of tests with different parameters were conducted. The equivalent coefficients of breaking force, breaking displacement, and net energy dissipation were defined to describe the potential relationship. Besides, sensitivity analyses were made. The results showed that, with the increase of impact velocity, the equivalent coefficients of breaking force decreased as a power function, and the equivalent coefficients of breaking displacement and net energy dissipation both decreased linearly. As the ring diameter increased, the equivalent coefficients of breaking force increased linearly, but the equivalent coefficients of breaking displacement and net energy dissipation both decreased linearly. With the increase of the aspect ratio of ring net, the equivalent coefficients of breaking force and breaking displacement decreased linearly and exponentially, respectively, and the equivalent coefficients of net energy dissipation decreased as a power function. With the increase of the ratio of loading head area to ring net area, the equivalent coefficients of breaking force increased as a power function, and the equivalent coefficients of breaking displacement and net energy dissipation decreased and increased linearly, respectively. The influence degrees of these parameters are as follows: impact velocity > ring diameter > aspect ratio of ring net > ratio of loading area to ring net area. Based on these four parameters, the equivalent coefficient formulas of static punching and dynamic impact were established.
