摘要
以某公司25 t汽车起重机车架作为研究对象,运用ANSYS有限元分析软件,通过分析车架在不同作业工况下的应力及变形情况,对车架进行局部优化。比较优化前后车架应力云图可以发现,每个工况下最大应力值都有不同程度的降低、应力分布更加均匀、结构更加合理。优化后的整机投放市场23台套,经使用无一车架失效的质量反馈。经过优化,车架单台重量减少了180 kg左右,降低材料成本约900元,达到了轻量化的目的。
In this paper, a 25 t truck crane frame was chosen as the research object, different work conditions of stress and deformation of the frame were analyzed by using the finite element analysis software-ANSYS to strengthen the high stress parts and simplify the low stress parts. It could be found that the maximum stress was reduced in varying degrees, the distribution of stress was more uniform, and the structure was more reasonable by comparing the frame stress contours in each condition before and after the frame was optimized. There was no failure quality feedback after 23 highly optimized sets were put into the market. After optimization, the single frame weight was reduced by about 180 kg and the material cost was reduced about 900$, and then the frame lightweight design was achieved.
