为了研究水力辅助破碎瓷砖和降噪机理,建立水射流冲击瓷砖模型,提出机械-水力联合作用下破碎瓷砖,并分析其机理。通过SEM分析得出噪声主要发生在瓷砖表面比较粗糙的地方。建立湿磨瓷砖降噪模型。由一系列干湿磨瓷砖噪声对比实验表明,湿磨瓷砖噪声性能优于干磨瓷砖,有显著的降噪作用。 In order to study the hydraulically-assisted broken tiles and the noise reduction mechanism, a water jet impact tile model was established, and the broken tiles under the mechanical-hydraulic interaction were proposed. The mechanism was analyzed. The SEM analysis shows that the noise mainly occurs in the rough surface of the tile. Establish a wet grinding tile noise reduction model. Comparison of a series of wet and dry ceramic tile noise experiments show that the wet grinding ceramic tile noise performance is better than dry grinding tiles, a significant noise reduction.
