列举了空气弹簧ANSYS仿真过程中存在的一些问题和难点。介绍了EQ6111空气弹簧的结构和材料特点，并针对性地建立了空气弹簧的有限元模型。针对空气弹簧分析过程中所存在的气压载荷问题，采取了多步分析的思路。在此思路的基础之上，采用离散求和法编写胶囊容积计算宏，应用于空气弹簧的垂向和横向静态力学性能分析，并将分析结果与试验结果和前人分析结果进行了比较，取得了较高的模拟分析精度，并且大大提高了仿真过程的连续性和可控制性。

An experimental study of heat transfer characteristics in a flattened copperwater mini-axial grooved heat pipe (AGHP) using a round AGHP with an outer diameter of 6mm and length of 210mm as the base case is reported. This AGHP was subsequently flattened to heights of 3.5， 3， 2.5 and 2mm. The temperature distribution along the axial distance, maximum heat transfer rate (MHTR), thermal resistance and evaporation heat transfer coefficient were experimentally determined for both AGHP and flattened AGHPs with different flattening height at several saturated vapor temperatures. The MHTR was found to decrease by 75% when the AGHP was flattened from a height of 6mm to 2mm. The thermal resistance was 0.08℃/W for both the round AGHP and flattened AGHP when the flattening height was greater than 2.5mm. When the AGHP was flattened to a height of 2mm, a significantly higher thermal resistance was observed. The evaporation heat transfer coefficient at the same saturated vapor temperature increased as the AGHP was flattened from 6mm to 3.5mm. However, when the AGHP was flattened in the range 3.5mm to 2mm, the evaporation heat transfer coefficient decreased.
