在机械、仪器和高技术密集型产品零件加工设备中,精密位移的研究受到重视。性能良好的试验装置是十分必要的。M2试验台采用微机技术、光电测量技术和数据分析与处理技术,使研究工作定量化。试验台研制成功后,曾做了法向高频激振对爬行抑制的研究。试验表明,只需很小的功率就可以消除爬行。这一实验引起同行专家的注目。 In mechanical, instrumentation and high technology intensive product parts processing equipment, the study of precision displacement attention. Good test equipment is essential. M2 test bench using computer technology, optical measurement technology and data analysis and processing technology, research work to quantify. After the successful development of the test bench, we made a research on the repulsive suppression of normal high-frequency excitation. Experiments show that crawling is eliminated with very little power. This experiment attracted the attention of peer experts.
