惯性平台环架对零件的刚度、强度的要求很高,传统铝合金材料已经很难满足新型平台的要求。对铝基复合材料早期性能和改良后的性能进行了研究,通过仿真分析及力学试验,验证了铝基复合材料通过二次变形加工的方法,有效提高了强度和延伸率,应用复合材料后,在大过载情况下能够有效抵抗变形,从而提高平台系统精度。
Inertial platform ring frame parts of the stiffness, high strength requirements, the traditional aluminum alloy material has been difficult to meet the requirements of the new platform. The early performance and the improved performance of the aluminum matrix composites were studied. Through the simulation analysis and mechanical tests, it was verified that the aluminum matrix composites through the secondary deformation processing method effectively improve the strength and elongation, the application of composite materials, In the case of large overloads can effectively resist deformation, thereby enhancing the platform system accuracy.
