| Abstract: | In order to improving the dynamic performance of the SL500/HZ ultra-precision surface grinding machining,the basic theory and methods of the experimental modal analysis was gotten from the basic theory of modal analysis.According to actual working conditions of the SL500/HZ ultra-precision surface grinding machine and the actual environmental conditions of the test,experimental modal analysis of the SL500/HZ ultra-precision surface grinding machine was made through the hammer testing,the modal parameters and mode shapes of the first stage to the eighth-order were obtained,the modal parameters of each order were analyzed,the weak links of the dynamic performance of the machine were found out.At last,the improvement program in the structure was designed for the weak link.The experimental results show that the research provides bases in the structure to improve the dynamic performance of the SL500/HZ ultra-precision surface grinding machine. |
