动车组盥洗室水盆台面裂纹分析研究

针对动车组盥洗室水盆人造石台面裂纹,调研发现,台面裂纹数量较多并且主要集中在背部接缝和台盆四角处。根据调研结果,对人造石台面进行仿真分析、拉伸强度测试、弯曲强度测试、落球冲击试验。试验结果表明,人造石台面符合标准要求,但是台面中的亚克力含量对台面强度有一定影响。根据分析和试验结果,提出了改进接缝粘接结构、加强支撑、选择高含量的亚克力台面等优化措施。

Analytical Study on the Washbasin Countertop Cracking Problem in EMU Lavatory

Aiming at the problem of artificial stone countertop cracks in EMU lavatory,survey has shown that a larger amount of countertop cracks and concentration are on the back seams and the corners of the basin. According to survey results,simulation analysis,tensile strength test,bending strength test and falling ball impact test on the artificial stone countertop was conducted. The test results demonstrated that the artificial stone countertop meets the standard requirements,but the content of acrylic in the countertop has a certain degree of influence on the strength of the countertop. Based on the analysis and test results,optimization measures such as improving seam bonding structure,strengthening support,and selecting high-content acrylic countertop were proposed.
