For the problem of inadequate terrain adaptability caused by the fixed structure of traditional helicopter landing gears, a new landing gear integrated for buffering actuation and walking with two stage buffering system was designed. The buffering function under multiple conditions was realized, the magnetorheological damper works to realize function in the conventional landing; the magnetorheological buffer and the oil-gas buffer work together to realize crashworthiness under the dangerous condition. A drop simulation model was established in the multibody dynamics software LMS Virtual.Lab Motion. The adaptive landing gear can adjust attitudes by two hydraulic actuating cylinders. The drop simulation analysis of the normal condition and the crash-resistant condition was carried out, and the buffer parameters were designed according to simulation data., the drop test was carried out under various conditions. Compared with the test and simulation results, the results show that the system’s buffering efficiency reached 85% and 75% respectively at two landing speeds. The adaptive landing gear can adjust to different attitudes actively, and it has good buffering performance at each attitude and a crashworthiness ability. The fact that the simulation and test findings were in agreement shows how well the multi-body dynamic model of the landing gear simulates the drop process.
