| Abstract: |
| Objective To propose the design scheme of pressure balanced equipment for the pressure balanced system of engine start tests in environmental laboratory, study the effect of pressure balanced equipment on climate test chamber pressure and optimize the design solution. Methods Pressure movement of climate test chamber under different structures was obtained through co-simulation of CFD and dynamics based on FLUENT and ADAMS. Results The climate test chamber pressure was affected by dynamic characteristics of pressure balanced equipment decided by its structure and force on pressure balanced equipment. Conclusion Change in flow field was clearly described by the co-simulation results. Reasonable design solution of pressure balanced equipment could ensure the chamber pressure in a regulated range, and the design solution proposed in this paper could meet the needs. |
