摘要
为分析自行车车架在危险冲击载荷作用下的安全性,使用三维造型软件建立了自行车车架前叉组合的三维实体模型,在ADAMS中完成虚拟样机的建立。为使仿真过程与实际情况更加接近,将车架作为柔性体处理。完成运动学分析后将提取的载荷文件导入ANSYS对车架加载,进行有限元分析。根据应力结果对车架结构设计进行安全性评估,对车架的结构设计提出改进方案,确保车架结构安全性和经济性。
In order to analysis the safety of bicycle frame under impact load, solid model of Frame^Fork assembly was set up with 3-D modeling software, and virtual prototype was established in ADAMS. The rigid bicycle frame was handled as a flexible body to make sure the simulation process closer to the actual situation. After kinematic analysis was completed, import load file of bicycle frame into ANSYS then finish finite element analysis. By analysis the stress distribution of frame to assess its safetiness, the paper provides an improvement program to ensure the safety and economy of frame structure. [ Ch,8 fig. 2 tab. 12 ref. ]
