Concrete Mixing Station Finite Element Analysis And Optimization Research

In the recent years, the urbanization is developed rapidly and the infrastructure construction is biggest than before. The demand of pre-mixing cement concrete is more and more in urban construction. The number of cement concrete mixing stations increase rapidly in order to meet the need of the pre-mixing cement concrete. The mechanical structure of HZS150C cement concrete mixing station is analyzed by ANSYS with the finite element method in order to crack down the problem of the construction of the cement concrete mixing stations according to the investigation of Zhonglian cement plant. The mechanical structure is optimized by the analysis result in order to make the reasonable structure and the operating stabilization ration.The following research contents are developed in this thesis:(1) The whole structure of mixing station is designed and the parameters are given. The FEM analysis method for space structure for statics and dynamics is investigated too.(2) The steel structure of mixing station is modeled by the ANSYS and analyze the internal force, reaction force, self-vibration characteristics and the amplitude of vibration.The mechanical structure is optimized on the basis of research results.(3) The main engine system is modeled with Pro/E. The load, stress, self-vibration and resonance characteristic are analyzed by ANSYS in order to find the reasonable structure of agitating shaft.(4) The force analysis of the bolts for the attachment between the main bodies is given, which can meet the need of strength.The force of the equipment of mixing station is investigated with FEM. The whole optimized structure is reasonable and operating stabilization ration. It is important to improve the performance of product and market competitiveness.
