摘要
研究热氧老化、自然老化、拉压疲劳老化等室内模拟老化试验对连续式弹塑性伸缩装置性能的影响,在仅考虑温度影响的情况下,拉压疲劳试验表明连续式弹塑性伸缩装置可用6～8年。
The influence of indoor simulating aging tests such as thermal oxygen aging, natural aging, tension and compression fatigue aging, etc on the performance of continuous elasto-plasticity extendable device is investigated. In the case only the influence of temperature is considered, the tension and compression test shows that the continuous elastoplasticity extendable device can be used for 6 - 8 years. fatigue
