Abstract

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.

动力H3直升机管状框架底盘静结构分析

汽车底盘的设计与开发在航空工业中具有十分重要的意义。这是由于它在静态和动态条件下支撑车辆主体结构的重要作用。它提供了足够的空间来携带飞行器的各种部件。因此，它应该足够坚固，能够承受不同类型的应力。本文利用CATIA V5对dyali H3型双座直升机管状框架底盘进行了建模，并利用Ansys静力结构软件对其进行了有限元仿真。这项工作的主要目的是对现有框架进行结构分析，使用导出的静载荷作用于管状框架上。分析的重点是采用静载的结构载荷，旨在以应力最小、性能最大的方式提高管状空间框架底盘的强度和现有模型的设计完整性。在相同的静荷载下，与现有框架相比，所提出的设计经历了更小的变形和应力。
