美标振动(冲击)测试技术应用分析与设备研制

为满足汽车检测行业用于检测汽车外部照明和光信号装置的振动设备之需求,解决如采用全进口设备成本高等问题,本文参照美国汽车工程师协会(SAE-international)推荐的技术标准SAE J577-2005,对该标准推荐的简图作了进一步的分析,提出了设计改进方案,并根据此方案研制出了全新的且符合SAE J577标准的振动测试台。该设备经一年的试用,证明了其改进方案有效且可行。

The purpose of this paper is to meet the vehicle inspection industry＇s requirements of the testing vibration machine for vehicle exterior lamps and light signal devices, and solve the problem of high cost on using imported equipment. After consulting standard SAE J577-2005 recommended by the SAE International, this paper further analyses the diagram in this standard, proposes a design improvement scheme, and develops a new vibration test machine conforming to SAE J577-2005 based on the scheme. After a one-year trial of the equipment, it was proved that the improvement scheme was effective and feasible.
