基于ANSYS的混凝土三维随机骨料生成方法研究
Research on 3 D random Aggregate generation method of concrete based on ANSYS
摘要
Abstract
In order to further study the three-dimensional generation and placement algorithm of concrete aggre-gate particles,a three-dimensional random aggregate building method based on ANSYS is proposed.This method can generate arbitrary convex polyhedron aggregates.First of all,the concrete aggregate feeding algo-rithm is controlled by the random number of the unit,and the randomness of this method is better;secondly, the radius and the angle of the aggregate are randomly generated by using the RAND function in MATLAB to make the generated random aggregate approximate to the real ones.Particles.To verify the effectiveness of the algorithm,the number of random aggregates of secondary and tertiary aggregates was calculated according to the Monte Carlo method to simulate three-dimensional aggregate particles of concrete.The results show that the particles put by this algorithm not only have the advantages of position randomness and shape diversity,but al-so have the advantage of random placement after prioritizing the mesh in the process of aggregate delivery,and can avoid repetitiveness in the calculation of aggregate overlap.Calculations.关键词
