For more than ten years, we have developed several series of products with an annual investment of not less than 8% of sales revenue, which has filled the domestic gap, broken the decades-long blockade and embargo of foreign countries and reached the world-class industrial scientific research level. 1999 The SA series switching power amplifier was first introduced in China. In 2002, it was the first in China to successfully develop a 5-ton electric vibration table with independent intellectual property rights and won the National Defense Science and Technology Achievement Award. In 2004, it broke the international monopoly, conquered the key technology of the large thrust water-cooled electric vibration test system, and successfully developed the international advanced 10 ton electric platform, which was commended by the leaders of the General Assembly Department and China Manned Space Engineering Office and became the backbone unit of military electronic components research and production. In 2005, the high acceleration impact test-bed with a height of 654.38+100000 g was born, which once again narrowed the distance between China and the world. In 2006, the first 20-ton electric platform in China was successfully launched. In 2007, the largest 40-ton electric table and 30-ton hydraulic table in China came out one after another. In 2008, the hydrostatic bearing three-axis resonant electric vibration system, multi-point parallel vibration control system and fully sealed water-cooling four-purpose electric vibration system were successfully developed, which filled the domestic blank.
