AbstractTo create and research the dynamic model of the helicopter. To simulate the processes, which occur under operation conditions. To determine the requirements for the dynamic model components. To study and test the technologies of modeling and research with ANSYS and MSC.ADAMS software products.
The dynamic model of the helicopter is a large assembly based on the modal component technology. Operation conditions were modeled as a transition process. The modal components were built with the help of finite element analysis (FEA) in ANSYS. Development and research of the dynamic helicopter model as a large assembly was carried out in MSC.ADAMS.
The research allowed obtaining force factors in the nodes of the dynamic model, vibrations and movement of the helicopter and its interaction with the airfield. Modeling shortcomings were identified.
An incomplete helicopter model with incomplete and simplified component models was developed. Thus the research results are of an experimental nature and can serve as a basis for further investigation.
The study allowed obtaining knowledge and practical experience of developing the entire dynamic helicopter model and its components. The directions and fields of further work were defined. An understanding about the technologies of modeling within ANSYS and MSC.ADAMS environments was obtained.
