摘要:
为了考察深空探测器同位素热源模拟样品在高温-冲击复合环境下的环境可靠性,研制了一套高温-冲击复合环境试验装置。该装置由温度加载系统、冲击试验系统、带有热防护功能的夹具和控制系统等组成。该装置可完成室温约500 ℃热载荷加载。利用该试验装置对同位素热源模拟样品进行了500 ℃、5 000次的高温-冲击复合环境试验考核,获得了产品温升响应曲线、冲击波形图等相关试验信息。试验结果表明该试验装置能够进行高温-冲击复合环境试验。

Abstract:
To study the reliability of radioisotope heat source in the high temperature-impact composite environment, a high temperature-impact composite environment test system is developed. The main parts of this design are temperature loading system, impact test system, thermal shield system and computer information collection system. The proposed system can provide heating temperature of 500 ℃. The simulated samples of the isotope heat source were tested at 500 ℃ andhigh temperature-impact composite environmental tests are performed for 5000 times. The response temperature rise response curve and impact waveforms are obtained. The results show that this system can accomplish high temperature-impact composite environment test successfully.
