摘　　要：为了实现弹载红外相机静态质心配平,在整机质量具有一定要求下,设计了一套数量少、质量轻、工艺性好、互换性优的配重负载组合。针对狭小空间体积的弹载红外相机设计出配重负载以及合理安排负载组合的安装位置,提出了先利用三维设计软件Creo4.0仿真出原始样机质心位置,再结合整机的质心要求,在空间两点采用力矩平衡原理计算出配重负载质量和质心应在位置的耦合关系,在总结归纳了配重负载设计原则之上,运用Creo4.0设计出配重负载方案。经过投图、加工、装配以及严格的质心测试论证,结果表明,该方法很好地实现了质心配平功能,使得弹载红外相机满足质心要求。这种静态质心配平思路相较于试配法具有快速高效、布局合理等优势。In order to realize the static centroid balancing of missile borne infrared cameras,a set of counterweight load combination with less quantity,light weight,fine technology and interchangeability is designed under requirements of the whole machine quality.In order to design the counterweight load quickly and efficiently and arrange the installation position of the load combination reasonably for the missile borne infrared camera with small space volume,a method is proposed to simulate the centroid position of the original prototype by using the three-dimensional design softwareCreo4.0,and then calculate the coupling relationship between the mass of the counterweight load and the centroid position by using the torque balance principle at two points of the space.On the basis of summarizing the design principles of counterweight load,the counterweight load scheme is designed by using creo4.0.After projection,processing,assembly and strict centroid test,the results show that the method can achieve the centroid balancing function well,and make the missile borne infrared camera meet the centroid requirements.Compared with the trial method,this static centroid balancing method has obvious advantages of high efficiency and reasonable layout.
