Objective To provide the basis for medical evaluation of spacecraft, and to measure the impact acceleration of return-cabin of spacecraft. Method A facility to measure the impact acceleration of 'SZ-3' and 'SZ-4' during landing was developed and the acquired test data were analyzed. Result The data of impact acceleration of return-cabins of 'SZ-3'and 'SZ-4' were accurately recorded during landing. Most reliable and scientific data were gotten. Conclusion This facility could validate and evaluate the specifications of relevant systems of spacecraft, and provided the scientific basis for the decision if 'SZ-5',the manned spacecraft, could be launched.
