使用一种新改进的老化试验装置,对两种型号的氟硅油FSO-2和FSO-A进行加速老化试验,对老化试验条件进行考察,并采用凝胶色谱(GPC)对氟硅油进行相对分子质量分析,考察油样性质随老化时间的变化。老化试验结果表明:250℃以下两种型号的氟硅油均未出现凝胶,250～300℃下两种油样均发生老化反应。并且,在300℃下,随着老化时间的延长,两种氟硅油的相对分子质量和相对分子质量分布都明显增加。通过GPC对老化规律的分析,得出在300℃下,FSO-2和FSO-A的老化机理一致,但FSO-2较为稳定,寿命较长。

动力总成是车身振动的主要来源,合理的悬置刚度和安装点位置对于降低车身振动,提高汽车乘坐舒适性十分重要。根据车身、悬置和动力总成参数,考虑车身悬置点动力学特征,建立整车悬置系统振动传递简化模型,分析车身悬置点导纳对动力总成传递到车身振动能量灵敏度,查找对输出功率流影响最大的导纳所对应悬置及方向,在车身车架有限元模型中计算悬置点位置改变对导纳影响大小,进而找出最能降低向车身传递功率流的悬置最优位置。灵敏度分析及有限元模型中的计算结果表明合理选择悬置安装点位置对于降低传递到车身功率流有一定的效果,对悬置最优位置的确定给出了合理的建议。

The development of flexible supercapacitors(FSCs) capable of operating at high temperatures is crucial for expanding the application areas and operating conditions of supercapacitors. Gel polymer electrolytes and electrode materials stand as two key components that significantly impact the efficacy of hightemperature-tolerant FSCs(HT-FSCs). They should not only exhibit high electrochemical performance and excellent flexibility, but also withstand intense thermal stress. Considerable efforts have been devoted to enhancing their thermal stability while maintaining high electrochemical and mechanical performance. In this review, the fundamentals of HT-FSCs are outlined. A comprehensive overview of state-of-the-art progress and achievements in HT-FSCs, with a focus on thermally stable gel polymer electrolytes and electrode materials is provided. Finally, challenges and future perspectives regarding HT-FSCs are discussed, alongside strategies for elevating operational temperatures and *** review offers both theoretical foundations and practical guidelines for designing and manufacturing HT-FSCs, further promoting their widespread adoption across diverse fields.
