The rescue platform can provide remote rescue materials and shelter facilities for victims who encounter sudden natural disasters, accidents, etc. within the delivery radius, and has the ability to increase the chances of survival of the victims. The rescue platform in this article is equipped with modular floating airbags to provide the rescue platform with long-term floating capabilities. When the rescue platform is working, it will cause great interference to its overall posture. In order to evaluate whether the floating performance, connection strength, and airbag strength of the current rescue platform can meet the requirements under such interference, the floating performance simulation of two working conditions was carried out. The simulation results show that under the two working conditions, the pitch angle of the rescue platform changes between ± 9°, and the maximum bag pressure of the airbag and the stress of the rope are within the safety limit, indicating that the current design state is feasible and subsequent tests can be carried out. This article provides theoretical support for the subsequent anti-interference performance test.
