Vibration reduction design method for mechanical equipment

Abstract

The invention discloses a vibration reduction design method for mechanical equipment. Parameter type selection of a vibration reduction device, design of the vibration reduction device and the equipment are combined, and the vibration mode, inherent frequency and static load maximum displacement of the vibration reduction device are obtained through modal analysis and static structure analysis. Vibration mode evaluation and vibration reduction efficiency calculation are conducted on the vibration reduction device in combination with the environment vibration working condition, and finally the vibration reduction device meeting the vibration mode, the vibration reduction efficiency and the static load maximum displacement is completed. According to the vibration reduction design method, effective vibration isolation can be conducted between the equipment and the environment vibration source, the vibration amplitude transmitted to the equipment from the vibration source is greatly attenuated, and therefore the influence of environment vibration on the equipment is reduced, and the stability and reliability of equipment operation are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration, and in particular relates to a vibration reduction design method of mechanical equipment. Background technique [0002] Mechanical vibration is the main cause of damage and failure of many mechanical, electronic, electrical and other equipment, which will reduce the service life and reliability of the equipment. In order to avoid adverse effects of mechanical vibration on equipment and improve the life, reliability and stability of equipment and products, vibration reduction design is an unavoidable problem. [0003] The existing vibration reduction design is mainly to increase the vibration reduction device or vibration reduction equipment, but the design of these vibration reduction devices or vibration reduction equipment can only be designed qualitatively, but it is difficult to calculate and evaluate quantitatively, and the vibration reduction effect is not ideal. Existing theo...
