摘　　要： 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。 Very high stiffness and strength are demanded for the gimbal rings of inertial platforms.The traditional aluminum alloy material can hardly satisfy the request of the new platform.The initial and improved property and performance of aluminum matrix composites are investigated with imitating analysis and mechanics testing.It is validated that the strength and extension rate of the aluminum matrix composite materials are improved significantly by secondary molding of machining method.After using the composite material,the accuracy of the platform is improved by remarkably reducing the transmogrification of the platform gimbal rings under over loading stress.
