| 摘 要： | 飞机机轮螺栓力矩是影响飞机起降的关键因素。研究设计了一种机轮螺栓力矩加载机构,并基于机构的理论危险工况,对其框架组件进行静力学分析。采用拓扑优化的方法对主要框架结构进行优化,并对优化后的框架组件进行静力学分析和两种工况下的瞬态动力学分析。计算结果显示,优化后的框架组件强度、刚度均满足要求,质量减少32.8%,为民航特种设备设计及应用提供了重要参考。

| Abstract: | The bolt torque of aircraft wheel is the key factor affecting aircraft take-off and landing. A kind of wheel bolt torque loading mechanism was studied and designed, and the static analysis of its frame components was carried out based on the theoretical dangerous working conditions of the mechanism. The topology optimization method was used to optimize and reconstruct the main frame structure, and the static analysis and transient dynamic analysis of the optimized frame components were carried out. The results show that the strength and stiffness of the optimized frame components meet the requirements, and the mass is reduced by 32.8 %, which provides an important reference for the design and application of civil aviation special equipment. |
