Embodiment Construction
[0035] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0036] Example: Refer to the schematic Figure 5 , Design and manufacture shock wave absorbing device. (a) Establish the finite element model of waveguide material as image 3 As shown, the model is divided into upper and lower layers. The upper layer is a titanium alloy thin plate, and the lower layer is a waveguide material that matches the impedance of the titanium alloy plate to verify the feasibility of wave penetration. The numerical simulation results are as follows: Figure 7 , The shock wave absorbing device can achieve 80% wave transmission, but there are still some reflections on the back.
[0037] (b) Fabrication of impedance-matching elastomers. The ...
