Abstract:
In order to expand the temperature test capability on the existing centrifuge platform with a swivel arm structure, an approach for designing an integrated acceleration-temperature environmental test system was proposed in this paper. In view of the uneven distribution of temperature field in the temperature chamber caused by the centrifugal overload and Coriolis acceleration, the flow field interference was carried out by adjusting the heat source position in the temperature chamber and increasing the airflow of wind turbine. The performance of the system was verified by the structural strength simulation and tests. The results demonstrate that the test system can conduct integrated environmental tests with acceleration of 0
g to 45
g and temperatures ranging from room temperature to 130 ℃, while maintaining the monitored temperature deviation within ±5 ℃. The above research may provide a reference for the design of integrated acceleration-temperature environmental test systems.
