多用途飞船返回舱虚拟振动试验研究
Virtual vibration analysis and verification of the re-entry capsule for a multi-functional spaceship
摘要
Abstract
The vibrations of a re-entry spacecraft capsule are investigated by using the virtual vibration software. Combining the finite element model of the capsule and the history experimental data acquired from Shenzhou-1, the virtual sinusoidal/random vibration experiments are carried out to test the capsule's ability of surviving the vibration environment during the launch stage. This analysis provides reliable and significant data for the optimized design of the capsule since the real vibration tests will not be carried out in the design stage. The model 1, which is before optimization, is found to have defects and the resonant response of the nodes in the Dadi region is too large to satisfy the experimental requirements. After the iterative optimization, the mode finally satisfies the design requirements. To reduce the cost and save time, instead of the real vibration test, the virtual vibration tests are beneficial. This is the first spacecraft designed based only on the virtual vibration in China.关键词
