Abstract: The basic concept,types and features of accelerated life tests were introduced.The methods of accelerated life tests for long-life spacecraft mechanisms,both in China and abroad, were reviewed.The characteristics of methods of accelerated life tests for both solid-lubricated and oil-lubricated long-life spacecraft mechanisms were analyzed.Solutions to some problems existed in quasi-accelerated life tests for long-life spacecraft mechanisms were put forward.

Key words: Accelerated life test, Solid lubrication, Liquid lubrication, Long life, Spacecraft mechanism, Test method
