"This is a high-definition optical system with special color scattered glass." Hu Xiangping, the leader of the company's technology, introduced that from the first product H-FK61 mass production in 2016, it iterative upgrade has been iterated to the fifth H-FK95.

In the 1980s, high -definition optical imaging technology was applied in the fields of cameras, cameras, monitoring and other fields. Foreign companies have the presence of high -definition optical glass markets produced by foreign companies because of the "eliminating the difference in imaging differences" technology. Up to 2,000 yuan/kg. The optical lens of high -definition cameras generally requires more than 10 optical elements, and the core glass components are produced by two Japanese companies. Although the technical level of the remaining glass components is not high, many domestic companies, including Xinhua Guang, can produce, but Japanese companies implement a binding sales strategy, which seriously limits the sales and industry development of domestic optical glass.

At the end of the 1990s, Xinhua Guang Company developed a high -definition imaging glass formula for special colors. Since 2014, the company has independently designed production lines suitable for fluoros glass continuously, and overcome key technologies such as inhibitory fluoride volatile and high -quality glass liquid preparation, which breaks through high -definition imaging bottlenecks for optical glass preparation. Visible light glass's second largest optical material scientific research and production base in China.

In recent years, Xinhua Optical Company has continued to increase investment in R & D, and cooperates with Huazhong University of Science and Technology and Shanghai Optical Machinery Institute to develop cutting -edge optical glass and special glass. In 2016, the high-definition imaging system used a low refractive index special color dispersion glass H-FK61 to achieve mass production, breaking the foreign technology monopoly, and the international market price dropped to 200 yuan to 300 yuan per kilogram.

On September 9th, in the production workshop of Xiangyang Zhongmo Motor Technology Co., Ltd., the reporter saw that the row of permanent magnet synchronous traction motors were placed in an orderly manner.

"The high -speed rail is a new business card in China, and the traction motor is the core of rail transits such as high -speed rail and subway." Li Weiye, deputy general manager of the company, introduced that in order to increase the power of the traction motor in a limited space to the maximum. In 2003, the preliminary work of the permanent magnet synchronous traction motor was launched. Due to foreign technology blockade, at that time, the relevant technical reference materials were almost zero.

In 2007, French Alstom Corporation set the fastest speed of 574.8 km/h with the new AGV train technology. The strength of the opponent further stimulated the determination of the chasing of the Motor motor to catch up.

The company forms a multi -disciplinary team including material science, electrical, magnetism, thermalology, and mechanics. It consists of more than 100 people such as senior engineering and doctoral and doctoral. echelon.

In 2009, the first subway permanent magnet traction motor was installed in Shenyang Metro. From 2014 to 2019, Xiangyang Middle Vehicle Electric Magic Synchronous Traction Motor completed the 300,000 -kilometer vehicle testing and carried out passenger operations on the high -speed rail, becoming the first high -speed train to load the permanent magnet motor in China.

At present, the power density density of the CRRC Motor High -speed Magnet Synchronous traction motor reaches 1.33 kW/kg, breaking the industry record of foreign companies; the energy conservation rate of the subway train loaded with permanent magnet traction motors exceeds 30%, reaching the international leading level; CRRC motor is on the orbit. The market share of trains permanent magnet motors has reached more than 90%. Congress loading applications on rail trains in more than ten cities across the country have greatly improved the technical level of rail trains in my country.

Daan Automobile Inspection Center -Hundreds of testing scenes flexibly switch

A driverless vehicle passed through the intersection at a speed of 60 kilometers/h. Suddenly a bicycle was inserted obliquely, and the driverless vehicle had an emergency brake ...
