[Abstract]:The iron water truck is a kind of type of vehicle derived from the logistics transportation in the metallurgical industry. It mainly takes on the role of transporting high temperature hot metal. The high temperature hot metal transportation mode mainly includes railway transportation, semi-trailer transportation and full hydraulic transportation. Full hydraulic iron water truck has strong carrying capacity and high reliability. It overcomes the shortcomings of traditional transportation, such as large turning radius, inflexible turning and large area, so it has a wide application market in the current hot metal transportation. It has become the development trend of hot metal transportation in iron and steel enterprises. The excellent electro-hydraulic control system and reliable mechanical structure of the vehicle are the guarantee of the long-term and reliable transportation of the iron water truck. This paper analyzes and studies the whole vehicle structure, the steering and adjusting system and the lifting system of the fully hydraulic iron water truck. The main research contents are as follows: (1) the key structure and safety design of the iron water truck are analyzed and studied, and the improvement scheme is put forward to ensure the safe driving of the whole car. The finite element analysis of the frame is carried out by using ANSYS software, and the structural weakness is found out. The modal analysis of the frame is carried out, the vibration distribution and the weak area of vibration resistance of the frame are determined, and the excitation frequency of the road surface and the engine under the frame of the iron water truck is analyzed and calculated. In order to avoid the resonance between the frame and the vibration source, the design basis is provided. (3) aiming at the deviation phenomenon of the steering system, a theoretical analysis is carried out, and the problems existing in the existing manual deviation control system such as low adjustment precision and complicated operation are discussed. This paper puts forward the automatic running and adjusting system, and simulates the automatic adjustment system by using Adams and AMESim software. Aiming at the problems existing in the synchronous lifting and lifting system of the iron and water truck, the reasons for the low lifting and lowering synchronization are analyzed. The key influencing factors are also studied. In view of the effect of accumulator charging and discharging on the synchronous accuracy, a new hydraulic system with pressure compensation is proposed. The validity of the improved scheme is verified by AMESim software and experimental research. 5) the data acquisition software and tools are used. The key parameters of the steering adjustment system and the lifting system are collected, and the rationality of the theoretical design is verified by experiments. The results obtained in this paper are of reference value and practical engineering significance for the lightweight design of iron water truck, the improvement of driving accuracy and the precision of body lifting and synchronizing.
