[0002] Rivets are nail-shaped objects used to connect two parts or components with a through hole and a cap at one end. In riveting, the riveted parts are connected by their own deformation or interference fit. They are often used to connect solar panels and brackets. In order to test the seismic performance of rivets in production, seismic simulation platforms are often required to simulate the damage caused by earthquake environments to rivets and test their seismic performance.
[0003] When testing rivets on existing seismic simulation platforms, the bracket is fixed to the table with screws, and the solar panel is then connected and fixed to the bracket with rivets. At the same time, a vibrator inside the body is used to drive the table to shake and vibrate to simulate an earthquake scenario. The seismic performance of the rivets is then measured by observing the damage and looseness of the rivets.
[0004] However, since the seismic performance value of rivets needs to undergo multiple earthquakes and multiple tests, and the number of screws required to fix the bracket is large, it may cause personnel to repeatedly disassemble and install the screws to replace the bracket, which may easily result in more steps required to replace the bracket and be more time-consuming and labor-intensive, affecting the efficiency of rivet detection.
