摘　　要：本研究使用应变花对自行车车架在疲劳测试和实际使用过程因受负载作用而产生的应变和应力进行了采集。通过应变和应力的分析和比对,对ISO 4210标准设定的车架疲劳测试项目的合理性进行了评价,同时也给出了测试项目改进的建议。本文对于提升车架疲劳测试的有效性和准确性有一定的借鉴意义,可以用于推动ISO 4210标准的修订以及相关测试设备的改进。This paper sampled the strain and stress of bicycle frame caused by the loads of fatigue test and real riding with strain rosette.Then this paper evaluated the rationality about bicycle frame fatigue test requirements in ISO 4210 based on the analysis and comparison of strain and stress. It also gave the opinions about the improvement of test requirements. This paper has certain reference significance for enhancing the validity and accuracy of frame fatigue test, and can be used to promote the revision of ISO 4210 standards and the improvement of related testing equipment.
