Dynali H3 Helicopter Tubular Frame Chassis Static Structural Analysis

The design and development of a vehicle chassis is of a high significance in the aviation industry. This is due to its vital role in supporting the main structure of the vehicle in both static and dynamic conditions. It provides enough space to carry the various components of the vehicle. Therefore, it should be strong enough to withstand the different types of stresses. In current work, the tubular frame chassis of Dynali H3 2-seater helicopter is modeled with CATIA V5 and simulated using Ansys Static Structural Software by implying Finite Element Analysis (FEA) method. The main aim of this work is to perform structural analysis on the existing frame using the derived static loading acting on the tubular frame. The analysis focused on the structural loading using static loading only aiming at improving the tubular spaceframe chassis strength and design integrity of the current model in such a way that stresses are minimum, and the performance is maximum. The proposed design experienced less deformation and stresses compared to the current frame under the same static loading.
