摘　　要：分析了航空机轮重量指标分配和估算方法,讨论了影响航空机轮重量的主要因素,提出最优重量概念,以及采用计算机辅助建模拓扑优化等优化减重技术途径,建立和实现基于强度和刚度设计准则和可靠性、寿命要求的航空机轮重量指标。同时提出建立沟通和协调机制,将轮胎和机轮纳入一个整体研制的管理思路。对于轮胎、机轮和刹车装置各部分重量提出合理分配考虑,建议轮胎重量占10%~15%,机轮轮毂占30%~45%,刹车装置占40%~60%为宜。Analyzed the distribution and estimation methods of aircraft wheel weight indexes,discussed the main factors affecting aircraft wheel weight,proposed the concept of optimal weight,and applying computer-aided modeling topology optimization and other weight reduced optimization methods to establish and realize the weight index of aircraft wheel based on the strength and stiffness design criteria,reliability and life requirements.Also,proposed to establish a communication and coordination mechanism to incorporate tires and wheels into a management idea of overall development.For the reasonable weight indexes distribution,suggested the tire weight should be 10%~15%,the wheel hub 30%~45%,and the brake unit 40%~60%.
