Shear strain is taken as critical plane parameter and strain energy is taken as damage parameter . 3. Through a series of comparisons, almost all the predicted data can be located in the double error strip of experimental data.

燃料电池在运输行业的解决方案正在被商业化 ➜ 燃料电池系统需要新的氢能解决方案来打破”氢能挑战” ➜ 降低每千克氢在应用现场的总成本是推举燃料电池解决方案的关键 •压缩氢 > 55 RMB/千克 ➜ 压缩氢占用太多空间，以至于限制了氢在重卡上实现应用 •有限的储氢空间降低了续航能力. HMSS Key Advantages 主要优势 1. TCO非常低: • 非常低的资本支出和运营成本，在重型卡车上以每公斤3至5美元的价 格生产氢气 2. 减低排放: • 无 NOx | 无 SOx | 无 PM (煤烟)| CO2 排放量显着减少ced. CO2 如果使用可再生甲醇) 3. 与压缩氢气相比，占用车辆较小的空间： • 结果是加燃料之间的驱动范围更大 4. 可扩展 : • 加氫站：50 – 500 kg 模塊化加氫站 • 車載：每个MHSS模块支持30 kW至300 kW的燃料电池 5. 简单/熟悉的原料储存 : • 无需储存高压氢气，提高了安全性

交通工具动力系统的演变. 醇类燃料是⾛走向“氢能社会”的必由之路. 甲醇增程式电动汽车. 甲醇增程电动汽车相对于传统汽车，燃料支出更少，尤其是货运物流中可极大降低物流成本。 以甲醇增程电动车为例，百公里燃料成本比传统汽车降低约三分之一以上. 甲醇增程式交通工具动力系统优势
