摘　　要：以42 m混凝土泵车臂架系统为研究对象,建立臂架系统的三维实体模型,分析其最危险工况下的受力情况,采用标准接触对模拟臂架系统的连接,通过有限元计算得到臂架系统的危险部位。在此基础上,对其危险部位的结构进行改进,即在1#弯板两侧加焊补强板,并对改进后的结构进行对比分析。结果表明,1#弯板处应力明显下降,最大应力减幅达到16.96%,实际使用中改进效果良好,可将该改进结构引入泵车臂架系统的设计中。Take the 42 m pump truck boom system as the subject,the 3D model of boom system was established to analyze force under dangerous working condition,then through the standard contact pairs simulating the joints and by means of the finite element analysis,the dangerous structure was obtained.Based on this,the dangerous structure was optimized and reanalyzed,namely,both sides of the 1# bending plate were improvd.The results show that,the stress of the 1# bending plate is decreased greatly after the structure is optimized,with the utmost reduction of stress 16.96％; the optimized structure works well in actual use,and it can be introduced to the design of the boom system.
