| Abstract: | The phenomena of POGO in China manned spaceflight was researched systemically. According to the complicated POGO issue found in our first manned spaceflight, the varying energy accumulator suppression scheme was first proposed to reduce the abnormal vibration of 8Hz that made important influence to the cosmonauts＇ lives, and brought comfort vibration scheme for the cosmonauts. |
