Description

technical field [0001] The invention belongs to the field of mechanical structure vibration isolation, in particular to a periodic vertical vibration isolation device. Background technique [0002] In industrial production and scientific research, precision instruments / equipment are widely used. In most cases, precision instruments have high requirements on the application environment during operation or work, and it is necessary to isolate or reduce the influence of external factors on the instrument as much as possible to ensure the normal operation of the instrument. [0003] Usually, external vibration will have a certain impact on the normal use of precision instruments, resulting in inaccurate work results, or even failure to work normally. Therefore, the vibration isolation problem in the use of precision instruments has also become a more difficult problem. According to the different excitation sources, the vibration isolation of precision instruments can be regard...

Problems solved by technology

For the isolation of medium and low frequency vibrations, conventional passive vibration isolation is difficult to have a good effect, especially for vibrations below 200Hz, the vibration attenuation effect is poor; although active vibration isolation technology can be used for low frequency vibration isolation of some small precision equipment It produces a certain effect, but the cost of active vibration isolation is high, the assembly is complicated, and the assembly space is limited; for some large equipment, due to its large static load, it is usually difficult to generate large energy to offset and suppress the active vibration isolation method. Vibration, resulting in poor vibration isolation effect, which limits the wide application of large equipment

[0005] In short, how to solve the isolation problem of medium and low frequency vibration is a thorny problem that needs to be solved urgently in the application process of precision instruments / equipment, which greatly affects the normal use of precision instruments and restricts their further development and application
