Experts approved world's first 1,000kN vibration shaker system developed by China

China has successfully developed the world's first 1,000kN electrodynamic vibration shaker system, announced the China Machinery Industry Federation (CMIF) on Monday.

The system was independently developed by Dongling Vibration, a leading Chinese mechanical environment and reliability test equipment manufacturer and overall solution service provider in east China's Jiangsu Province.

Vibration test systems are mainly used to test the reliability of equipment components by simulating real working conditions of vehicles and facilities such as rockets, satellites or planes. Such systems are indispensable for aerospace, transportation and other industries.

To date, this vibration shaker system has done testings for plane engines and a satellite weighing over 15 tonnes.

"We can only do feasibility testing of small components on 500 kN to 600 kN vibration test systems. Fatigue tests for a machine are beyond their capacity. Therefore, we are in dire need of test systems with greater forces, such as this 1,000 kN system, " said Ye Tengbo, chief engineer of Dongling Vibration.

As China has been marching towards greater achievements in aerospace, the weight and size of aerospace equipment continue to increase, and the structure becomes increasingly complex. All this means higher expectations for test system manufacturers.

"This is the first-ever 1,000 kN vibration test system in not just China but the whole world, symbolizing the latest technological breakthrough in vibration testing. We need such systems for our current and future development. For example, they are needed when we test the durability of components for aerospace vehicles, ships, rail vehicles like high-speed rail, and cars. Such testing systems are indispensable as our country is trying to develop high-end technologies. Therefore, it's fair to say that the successful operation of this system has paved the way for the high-quality development of high-end equipment in China," said Zhai Wanming, an academician from the Chinese Academy of Sciences.

Shortages of supplies and personnel hampering a quick response to an ongoing Ebola outbreak in Central Africa are the biggest public concern, according to a recent online survey conducted by the China Global Television Network (CGTN).

The survey was carried out to assess public worries surrounding the Ebola outbreak in the Democratic Republic of the Congo (DRC) and its neighbor Uganda.

According to the survey findings, 31 percent of respondents identified the lack of supplies and personnel delaying a quick response to Ebola control as their primary worry, ranking it highest among the options presented in the poll.

Meanwhile, anxiety regarding the epidemic worsening and the risk of a broader global crisis were tied at 28 percent each. Furthermore, 13 percent of those surveyed expressed their greatest fear that the virus could become more deadly.

The Ebola virus is highly contagious and causes symptoms including fever, vomiting, diarrhea, generalized pain or malaise, and in severe cases, internal and external bleeding.

The DRC had reported a total of 344 confirmed cases of Ebola, including 60 deaths, and Uganda a total of 15 confirmed cases, including one death, according to the World Health Organization (WHO) on Wednesday.

WHO declared the Ebola outbreak in the DRC a public health emergency of international concern on May 17. The current outbreak is caused by the Bundibugyo strain of the Ebola virus, for which there is currently no approved vaccine or specific treatment.

The DRC has faced repeated Ebola outbreaks since the virus was first identified near the Ebola River in 1976. The latest Ebola outbreak is the 17th in the DRC since 1976.
