我们研究了加热温度和加热方法对软金属氢化物致动器在紧急情况下作为救援千斤顶的操作的影响。致动器在大约50 - 80 ° C的热量下操作，并且不需要电力或操作者的体力消耗。操作时间可以通过调节加热温度和/或吸氢合金的量来调整，在较高的操作温度和较大的合金量下观察到更快的操作。对实际使用的拟议救援千斤顶热源的合适候选者进行了审查，从可储存性、简单性和加热效率的角度来看，生石灰是最实用的。该千斤顶使用15克合金和生石灰热源，在没有电力或人力的情况下，在一分钟内成功地将100公斤的重物顶起50毫米。
We investigate the effect of heating temperature and heating method on the operation of a soft metal hydride actuator as a rescue jack for application in emergency situations. The actuator is operative with heat of around 50–80 °C and does not require electricity or physical exertion of an operator. The operation time can be tuned by adjusting the heating temperature and/or the amount of hydrogen-absorbing alloy, with faster operation observed at higher operating temperatures and with greater amounts of alloy. Suitable candidates for the heat source of the proposed rescue jack for practical use were examined, with quicklime being the most practical from the perspective of storability, simplicity, and heating efficiency. With 15 g of alloy and quicklime heat source, the jack successfully jacked a weight of 100 kg by 50 mm within a minute without electricity or human power.
