The invention provides a horizontal two-degree-of-freedom vibrating table, which includes a vibrating table, a second vibration-isolated linear guide rail, a transmission saddle, a first vibration-isolated linear guide rail, a slider, a third vibration-isolated linear guide rail, a stand, and a second vibration-isolated linear guide rail. A driving device and a second driving device; the side wall of the vibrating worktable is provided with the first vibration-isolation linear guide rail, the slider is slidably connected to the first vibration-isolation linear guide rail, and the upper end surface of the transmission saddle The second vibration-isolation linear guide is provided, the lower end surface of the vibration table is slidingly connected with the second vibration-isolation linear guide, the upper end of the platform is provided with the third vibration-isolation linear guide, and the transmission The lower end surface of the saddle is slidingly connected with the third vibration-isolated linear guide rail; the first driving device and the second driving device are arranged on the upper end surface of the platform, the first driving device is connected with the transmission saddle, and the second driving device connected to the slider. The invention can effectively realize the vibration with two degrees of freedom not interfering with each other, is safe and reliable, and has low failure rate.
Description
technical field [0001] The invention relates to the field of vibration tables, in particular to a horizontal two-degree-of-freedom vibration table Background technique [0002] Vibration phenomena are ubiquitous in our lives. Vibration problems affect product quality and cause products to fail during service. Therefore, research on vibration has received more and more attention. Vibration test benches can provide a vibration simulation environment to control product vibration Perform performance research under state. [0003] At present, most of the horizontal test benches have one degree of freedom, and it is impossible to realize two horizontal degrees of freedom to simultaneously vibrate the environment, resulting in a discrepancy between the test simulation and the actual operating state, and the structure of the multi-degree-of-freedom test bench is complex, the cost is high, and large-stroke motion cannot be realized .
