Research on the Optimization of Porosity in Resin Mineral Composite

Abstract:

With good vibration alleviating properties, resin mineral composite (RMC) has been used to produce precision machine tool beds to satisfy the requirements of machining accuracy. Aggregate is one of the key components in RMC to bear loads, its gradation design determines the overall mechanical properties of the composite directly. In this article, an optimal method to determine critical dimension of screen holes is proposed based on Euclidean geometry and Particle interference theory, and the corresponding proportion of each component is adjusted on the basis of fractal theory. Variation tendency of porosity corresponding to different fractal dimension is obtained by using simulation method. On this basis, image processing technology is used to validate the aforementioned assumptions. Experimental results show that the optimal design has smaller porosity performance, which is consistent with the simulation results.
