Abstract讨论了TC-2卫星探测伸杆在技术状态更改中的结构和力学问题,并对TC-2卫星探测伸杆锁紧支座进行了模态分析、结构静强度计算和解锁机构展开的仿真分析.结果表明,伸杆锁紧支座在更换火工切割器后,支座频率变化不大,不会对整星的基频产生影响,改进后的锁紧支座结构能够承受动载荷,最大应力和应变均在材料的许用范围之内,锁紧支座在打开过程中不会与任何零件发生干涉,满足卫星对伸杆部件的要求.
Other AbstractA highly reliable two-segment deployable boom has been developed and manufactured for the Double Star Program.Two spacecrafts,one for equatorial,the other for polar orbit are equipped each with two mechanisms.One boom deploys two flux-gate magnetometers,the other a search coil magnetometer.The paper discusses the structure and mechanical problems of TC-2 satellites exploring booms in technical state improving design,and analyzes the mode,structure static strength as well as the clamp expanding process of exploring boom in TC-2 satellite.Results show that the boom clamps frequency only had small change after altering the pyrotechnical rod cutter and it would not have influence on the satellites frequency.The improved clamp can bear dynamic load, and its maximal stress and strain are all within the allowed range of material.Moreover,the clamps do not intervene with other parts when they are deployed,which can meet the satellites request.
