Embodiment Construction
[0060] The invention provides a multi-parameter optimization evaluation method for the best vibration isolation effect of a rubber vibration damping pad, which will be described below in conjunction with the accompanying drawings. The research results based on the analysis of the noise spectrogram show that the stiffness and damping characteristics of the rubber material will change with the frequency of the excitation force, which is the dynamic characteristic of the rubber material; this dynamic characteristic is the main parameter to evaluate the vibration reduction effect.
[0061] figure 1 Shown is the general technical roadmap, which shows the multi-parameter evaluation and optimization of the optimal vibration isolation effect of the rubber vibration damping pad. The actual test data is optimized and verified, and (1) the mechanical model of the basic principle of vibration absorption is established respectively; (2) the frequency spectrum and attenuation rate data of d...

The invention discloses a multi-parameter optimized evaluation method for an optimum vibration isolation effect of a rubber damping pad in the technical field of optimized selection of the rubber damping pad. According to the method, shown by the analysis and research result of a noise pattern, stiffness and damping characteristics of a rubber material are dynamic characteristics which can be changed along with frequency changes of an exciting force; the dynamic characteristics are major parameters for evaluating a damping effect. In a general technical route, by adopting the combination of actual test data verification and a comprehensive quality evaluation model, statistical analysis is performed to obtain an evaluating result summary sheet, and comprehensive optimized evaluation is performed. According to the multi-parameter optimized evaluation method for the optimum vibration isolation effect of the rubber damping pad disclosed by the invention, through a mechanical model established according to the working condition of the rubber damping pad, the rubber damping pad is simplified into a damping system with a single degree of freedom; by adopting the damping system, a damping coefficient is calculated, and the method is simple. A basis is provided for the equipment damping system adopting the rubber damping pad to calculate the damping coefficient, and therefore, equipment accident rate caused by poor consideration of the damping coefficient is reduced.
Description
technical field [0001] The invention belongs to the optimization and selection technology of rubber vibration damping pads, in particular to a multi-parameter optimization evaluation method for the optimal vibration isolation effect of rubber vibration damping pads. Background technique [0002] With the development of modern industry and construction, the urban noise in our country is increasing year by year. Noise not only interferes with people's life, study and work, but also endangers people's physical and mental health, causing various diseases, and serious cases can cause permanent hearing loss or even deafness. At the same time, noise also directly affects the quality and use effect of the product itself, increases energy consumption, and shortens the service life of the product. Therefore, it is necessary to control the noise. [0003] According to the mechanism of noise generation and transmission, noise control technologies can be divided into the following thre...
