摘要

通过隔振理论分析,设计了偏心电机和电磁激振器两种激振试验方案,并讨论了两种激振方案中振级落差和插入损失的关系;分别对直骨架结构和曲骨架结构的夹芯复合材料基座模型进行了激振试验;通过频响分析比较了两种结构形式基座的固有特性;讨论了两种激振方案下基座的隔振效果,结果表明两种结构形式的夹芯复合材料基座均具有较好的隔振效果,且能够有效抑制高频共振。

Abstract

The eccentricity vibrator system and electromagnetic vibrator system. was designed through the analysis of vibration isolation theory. The relationship between vibration level difference and insertion loss was discussed in different vibrator system. By the vibrator experiment of the vertical brace sandwich base and the crooked brace sandwich base, the property character of composite sandwich base was analyzed. The isolation effect of sandwich base was discussed in different vibrator. The result indicated that the sandwich base had superiority vibration isolation effect and can restrain the resonance in high frequency.
