The invention provides a horizontal two-degree-of-freedom vibration table. The horizontal two-degree-of-freedom vibration table comprises a vibration workbench, a second vibration isolation linear guide rail, a transmission sliding saddle, a first vibration isolation linear guide rail, a sliding piece, a third vibration isolation linear guide rail, a rack, a first driving device and a second driving device. The first vibration isolation linear guide rail is arranged on the side wall of the vibration workbench, the sliding piece is connected with the first vibration isolation linear guide railin a sliding mode, the second vibration isolation linear guide rail is arranged on the upper end surface of the transmission sliding saddle, and the lower end surface of the vibration workbench is connected with the second vibration isolation linear guide rail in a sliding mode. The third vibration isolation linear guide rail is arranged on the upper end surface of the rack, and the lower end surface of the transmission sliding saddle is connected with the third vibration isolation linear guide rail in the sliding mode. The first driving device and the second driving device are arranged on theupper end surface of the rack, the first driving device is connected with the transmission saddle, and the second driving device is connected with the sliding piece. Two-degree-of-freedom non-interfering vibration can be effectively achieved, safety and reliability are achieved, and a failure rate is low.
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 .
