Rotary vibration control simulation and experiment research on the boom of concrete pump truck

This paper proposes a method on predicting the remaining useful life (RUL) of a concrete piston of a concrete pump truck based on probability statistics and data-driven approaches. Firstly, the average useful life of the concrete piston is determined by probability distribution fitting using actual life data. Secondly, according to condition monitoring data of the concrete pump truck, a concept of life coefficient of the concrete piston is proposed to represent the influence of the loading condition on the actual useful life of individual concrete pistons, and different regression models are established to predict the RUL of the concrete pistons. Finally, according to the prediction result of the concrete piston at different life stages, a replacement warning point is established to provide support for the inventory management and replacement plan of the concrete piston.

This paper takes the five –link concrete pump boom as the research object, and transforms its trajectory planning issue into a multi-object optimization problem. Using intelligent hill climbing algorithm and genetic algorithm, and integrating them closely to ensure real-time online planning for the pump truck effectively, and make the planned motion trajectory for the boom is global optimized under particular constrained conditions. Simulation and performance comparison experiments show that this hybrid algorithm is practical and effective, which offers a new approach for the trajectory planning problem of concrete pump truck.

Concrete Pump

This research presents structural design and analysis results of applying a composite boom structure on a Concrete Pump Truck (CPT). Carbon Fiber Reinforced Plastic (CFRP) is used to complete the structural design of the end boom to reduce the weight of the CPT. The weight of the newly designed end boom is reduced by 32% compared to the original steel component. Structural analysis is accomplished by applying static load combinations of self-weight of the boom and the weights of the pipes, the concrete and the drain hose. The results show that the tip deflection is reduced by 30% compared to the conventional end boom. Also, equivalent stress is considerably lower than the conventional design. Composite failure evaluation of the CFRP end boom is conducted by post-processing the stress results using Puck’s failure criteria. The evaluation results show that the design criteria are met on the static load of the pump truck. Specifically, it is expected that fiber failure and inter fiber failure of the boom do not occur under loading conditions according to the design evaluation results.
