- 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.
