摘要:
以某5节臂的45m混凝土泵车为研究对象,采用实体单元与接触单元相结合的方法模拟各臂架之间的连接,板壳单元和梁单元用于模拟泵车其余结构,建立了整车有限元计算模型.通过力学分析得出了臂架水平且垂直于支撑点对角线时为泵车危险工况.在危险工况下对该泵车整体结构进行了有限元强度分析.计算结果表明:连接销处和臂架油缸支座处易发生大应力.根据计算结果进行了现场试验,试验结果表明计算分析与测量值相当吻合.
Abstract:

Taking a 5m concrete pump truck with 45 sections of arm as the research object, the method of combining solid unit and contact unit is used to simulate the connection between each boom, and the plate and shell unit and beam unit are used to simulate the rest of the structure of the pump truck, and the finite element calculation model of the whole vehicle is established. Through mechanical analysis, it is concluded that when the boom is horizontal and perpendicular to the diagonal of the support point, it is a dangerous working condition of the pump truck. The overall structure of the pump truck was analyzed by finite element strength under dangerous working conditions. The calculation results show that large stresses are prone to occur at the connecting pin and the boom cylinder support. Field tests were carried out according to the calculation results, and the test results showed that the calculation analysis was in good agreement with the measured values.
