织物芯增强轻型输送带的固有特性分析

Inherent Characteristics Analysis of Fabric Core Reinforced Light Conveyor Belt

以织物芯增强轻型输送带为研究对象,利用ansys软件对其进行固有特性分析,得到托辊间距、预紧力、载重物体质量密度对输送带固有频率影响的规律。研究表明:1织物芯增强轻型输送带的模态与其他输送带的模态基本相同;2托辊间距较小时,较小的预紧力对输送带前四阶固有频率的影响比较大;3预紧力较大时,较大的托辊间距对输送带前四阶固有频率的影响比较大;4物料质量密度不大时,物料质量密度对输送带前四阶固有频率的影响比较大。研究结果可为该类输送带的应用提供有价值的参考。

The natural frequency of the core fabric-reinforced light conveyor belt was studied by using ANSYS software, and the law of the influence of the distance between the rollers, the preload and the mass density of load on natural frequency of the conveyor belt was obtained. The results show that ：（1）the modal of the core fabric-reinforced light conveyor beh is basically the same as those of other belts;（2）the smaller preload has more influence on the former four-order natural frequency of belt when the distance between the rollers is smaller;（3）the larger distance between the rollers has more influence on the former four-order inherent frequency of belt when the preload is larger;（4）the mass density has more influence on the former four-order inherent frequency of belt when it is not large. The above results can provide valuable reference for the application of such kind of conveyor belt.
