摘要

目的为了降低包装托盘在运输过程中的特定频段高振动幅值响应。方法依据该类包装托盘的实际装配约束下的固支特征,随后对该类托盘结构加以模态分析,获得其模态特性而后进行模态叠加而得到该类托盘系统的振动传递结果;而后在明确不同T型振子结构耦合状况下的包装托盘结构动力学特性,同样分别对其进行振动传递结果分析,最后将统计所有类型下的结果,总结具有振子吸振作用的包装托盘动力学变化规律。结果通过对比在增加T型振子前后的2种结构动力学特性可知,在增加T型振子的前提下包装托盘有效实现了对前2阶共振峰进行高效抑制,明确不同振子结构耦合作用,有效抑制了共振频率处的振动抑制。结论通过上述结构仿真分析,可得到包装托盘在增加T型振子耦合作用机制下的动力学特性及振动传递变化规律,为同类包装托盘设计提供新思路。

Abstract

The work aims to reduce the high vibration amplitude response of packaging trays in specific frequency bands during transportation. Based on the fixed support characteristics under the actual assembly constraints of this type of packaging tray, the modal analysis was conducted to tray structures to obtain its modal characteristics, and then the modal superposition was performed to obtain the vibration transmission results of the tray system. Next, the dynamic characteristics of packaging tray structures under different coupling conditions of T-shaped oscillator structures were clarified, and the vibration transmission results were analyzed separately. Finally, the dynamic changes of packaging trays with oscillator absorption effects were summarized for all types. By comparing the dynamic characteristics of the two structures before and after a T-shaped oscillator was added, it was concluded that the packaging tray effectively suppressed the first two resonance peaks under the premise of adding a T-shaped oscillator, which clarified the coupling effect of different oscillator structures, and effectively suppressed vibration suppression at the resonance frequency. Through the above structural simulation analysis, the dynamic characteristics and vibration transmission changes of packaging trays under the coupling mechanism of T-shaped oscillators can be obtained, providing new ideas for the design of similar packaging trays.
