Embodiment

[0048] 1. Vibration damping test

[0049] The inventor artificially tests the vibration attenuation characteristics of the bonded steel plate, hangs the bonded steel plate sample, applies vibration to the sample with an impact vibratory hammer, and obtains as follows: Figure 3a , Figure 3b , Figure 3c to Figure 8a , Figure 8b , Figure 8c For the frequency response function curve shown, the 1st, 2nd or 3rd order natural vibration number and the loss coefficient in each natural vibration number are obtained from this frequency response function curve by using the half maximum width method. During the test, in order to reduce the measurement error, the measured value was obtained through 3 tests for each sample. The samples used were a single STS steel plate (refer to Figure 3a , Figure 3b , Figure 3c ), STS bonded steel plate (refer to Figure 4a , Figure 4b , Figure 4c ), a single Cu steel plate (refer to Figure 5a , Figure 5b , Figure 5c ), Cu bonded ...

Abstract

The inveition relates to a bonded plate, especially a bonded having excellent sound-absorbing, vibration-damping, and processability. The bonded plate is manufactured by bonding a surface plate and a backing plate backing the surface plate, by an adhesive resin haivng a preset viscosity and excellent sound-absorbing and vibration-damping performance. Thereby, the invention can obtain excellent sound-absorbing and vibration-damping functions from the material, can remarkably reduce the cost of production, and can secure formability equal to that of the conventional steel plate, can further achieve excellent processablity, and can be produced into products by all the conventional processing methods.

Description

technical field [0001] The present invention relates to a bonded steel plate, in particular to a bonded steel plate excellent in vibration damping, sound absorption and processability, using an adhesive resin with a predetermined viscosity and excellent sound absorption and vibration damping to bond the surface plate and support the The support plate of the surface plate is manufactured, which can obtain excellent vibration damping and sound absorption from the material itself, which can greatly save manufacturing costs, and has the effect of replacing high-priced steel in the past. It has excellent formability and can be applied to all previous products. Forming processing methods to produce products. Background technique [0002] Generally speaking, the sound insulation, sound absorption, vibration reduction, and heat insulation properties of a single steel plate are very poor, and there are many limitations, especially in the wide use of products exposed to noise, vibrati...
