生物基尼龙玻纤材料在汽车镜座支架上的应用

Bio-based Nylon Glass Fiber Material in Automotive Mirror Holder Bracket Applications

文章简要概述了后视镜的结构及构造,为响应国家的节能环保提倡,采用新型生物基尼龙玻纤复合材料取代常用的铝合金材料,对镜座支架做了全新的网格状设计。并利用常用的有限元仿真软件对后视镜总成进行模态分析,以验证材料的可靠性和设计的合理性。在已生产的成品基础上,对材料进行变更,设定生物基尼龙玻纤材料与铝合金材料为前提条件,比较两者模态分析结果。结果显示模态分析结果相差无几的情况下,本方案的材料成本更低,制造环节更加简化,有利于缩短制造周期、降低制造过程成本,并且模具设计方式及工艺手段更丰富,为产品结构复杂性提供基础。

The article briefly outlines the structure and construction of the rearview mirror.In response to the country's energy-saving and environmental protection advocacy,uses a new type of bio-based nylon fiberglass composite material to replace the commonly used aluminum alloy material,and makes a new grid-like design for the mirror base bracket.And the modal analysis of the rearview mirror assembly is carried out by using the commonly used finite element simulation software to verify the reliability of the material and the rationality of the design.In this article,on the basis of the finished product,the material is changed,and the bio-based nylon glass fiber material and aluminum alloy material are set as the prerequisites,and the modal analysis results of the two are compared.The results show that when the modal analysis results are almost the same,the material cost of this scheme is lower,and the manufacturing process is more simplified,which is conducive to shortening the manufacturing cycle and reducing the cost of the manufacturing process,and the mold design methods and process methods are more abundant,which provides the basis for the complexity of product structure.
