Description

technical field [0001] The invention relates to an experimental device, in particular to a non-contact vibration excitation experimental platform with adjustable full angle and distance. Background technique [0002] The mechanical system vibration experiment platform is used to simulate the environment in which mechanical parts are in the actual working process. It is used in many scientific experiment fields, including vibration resistance test, reliability experiment, vibration simulation analysis and fatigue experiment of various mechanical equipment. , material characteristic test, fault diagnosis and life prediction, etc. Most of the vibrating tables currently available on the market and existing in various scientific research institutions are contact vibration tables. The vibration excitation equipment of this type of experimental platform usually needs to use the transmission rod to contact the excited part to transmit the excitation signal. Therefore, this type of v...

AI Technical Summary

Problems solved by technology

At present, in the existing non-contact vibration test platform for vibration experiments on moving parts, there are mainly the following problems: the non-contact vibration exciter is fixedly installed, and its installation position cannot be flexibly changed according to the position of the moving parts, which leads to The distance between the exciter and the excited part cannot be adjusted precisely

When the distance between the exciter and the excited part is too close, it is easy to cause the vibrator to be directly adsorbed on the excited part, causing the excitation experiment to be interrupted. When the distance between the vibrator and the excited part is too far, the excited The excitation signal received by the component is poor, and the excitation effect is not obvious

The above two situations will affect the authenticity and accuracy of the experimental data, so that the experimenters cannot obtain correct experimental results based on the experimental data

The fixed installation form of the non-contact vibrator can only perform one-way excitation experiments on the excited parts, and cannot conduct full-angle excitation experiments. The obtained experimental data is single, which cannot meet the needs of scientific research
