摘要
本文利用结构振动理论对自行车车架与前叉组成的车体结构系统进行了振动特性分析,计算了前叉的动应力.研究表明:前叉质量的合理分布,可以改善其振动响应,动应力明显下降.并对车体结构系统做了振动对比试验.可为优化自行车车体结构的动力学特性提供依据.
In this paper, vibration characteristic analysis is carried out for the system of bicycle structure, composed of its frame and fork. The dynamic stress in the fork is calculated. It is illustrated clearly that the rational mass distribution of the fork may decrease its vibration response comparison test for the bicycle structures is conducted. The result is helpful to the dynamic optimization for the bicycle structure.
