摘　　要：空间相机传统的机械加工方式由于设备的限制,会对零件的结构设计产生一定的工艺约束,对于相机中复杂度较高的光机部(组)件,这些限制和约束可能会使其无法实现传力路径和力学性能的最优设计。文章从这一角度入手,通过3D打印工艺释放相机设计端的自由度,并结合拓扑优化完成了空间相机的一体式结构设计;最后进行了各种工况的有限元分析,并完成了相机加工制造,从而验证了3D打印工艺在提升传统空间光学相机轻量化率、减少相机组件数量等方面的优越性和可行性。In order to satisfy the needs of vehicle launching and on-orbit operation,the lightweight design has always been a key point to space cameras.However,it is usually restricted by the traditional machining equipment.For complex structure parts and optical components,these restrictions may be a limitation to achieve the optimal design of the load-transferring path and mechanical property.From this point of view,the degree of freedom is released for the designers by using 3D printing,and the structure design of an integrated space camera is finished through topology optimization.Lastly,the finite element analysis under various load cases is performed and the camera is manufactured.Therefore,the advantage and feasibility of the application of 3D printing in traditional space optical camera are verified to increase lightweight rate and reduce the part number.
