摘　　要：直升机起落架着陆性能直接影响直升机着陆载荷计算及机身设计,目前主要通过落震试验实测起落架的着陆性能。为了预先分析滑橇式起落架着陆性能,采用RADIOSS/HyperMesh模态分析平台,建立滑橇式起落架的落震仿真模型,进行着陆性能仿真计算。并设计了滑橇式起落架落震试验,实测起落架的落震性能参数。通过仿真分析结果与试验实测数据对比,验证了基于RADIOSS分析平台进行起落架着陆性能分析方法在工程上的可行性,同时通过仿真计算结合实测结果得到了滑橇起落架的着陆性能参数,为后续起落架进一步优化设计提供参考。The landing performance of sled landing gear helicopter directly affects the landing load calculation and the airframe design.At present,the landing performance of landing gear was mainly measured by falling test.In order to pre-analyze landing performance of skid landing gear,simulation analysis technology and RADIOSS/HyperMesh modal analysis platform were used to establish a sled landing gear landing simulation model and obtain relevant parameters.The sled landing gear drop test was designed in the later stage to measure landing gear fall performance parameters.By comparing the simulation results of the model with the test data,the engineering feasibility of the calculated results of the RADIOSS solver was not only verified,but also the performance parameters of the skid landing gear were obtained,which provided a reference for the optimal landing gear design.
