Abstract
The invention relates to a damping vibration attenuation performance test platform and a damping vibration attenuation performance test method. The damping vibration attenuation performance test platform is used for detecting the damping performance of a rolling linear guide rail pair system and comprises a base, a detection platform and a vibration excitation assembly; the detection platform is arranged on the base, the detection platform comprises a base, a workbench, a driving assembly and a portal frame, the rolling linear guide rail pair system is arranged between the base and the workbench, the driving assembly is arranged on the base and drives the workbench to move in the first direction, and the portal frame is arranged on the workbench in a crossing mode and moves in the first direction; and the vibration excitation assembly is arranged above the workbench and comprises a vibration exciter and a vibration excitation sliding rail, the vibration excitation sliding rail is arranged on the portal frame, the vibration exciter is used for impacting the workbench, the vibration exciter is arranged on the vibration excitation sliding rail and moves in the second direction, and the second direction is perpendicular to the first direction. Through the movable vibration exciter, damping performance detection is carried out under dynamic and static conditions, the test range is expanded, the detection precision is higher, and the application range is wider.
Description
technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a damping and vibration reduction performance test platform and a test method thereof. Background technique [0002] my country's high-end high-end equipment manufacturing industry is still facing the embarrassing situation that the key equipment and parts are heavily dependent on imports, the static and dynamic characteristics of domestic high-end CNC machine tools are poor, and the core technology of basic components is controlled by others, which has always restricted the long-term and healthy development of my country's high-end CNC machine tools. At present, my country's existing rolling functional component products, especially the rolling linear guide pair, still face a serious shortage of production capacity, low grade, poor reliability, and weak technological innovation capabilities. Imported products are still in a dominant position, which has become a c...
