The cold-formed of thin-wall channel steel columns which have large width to thickness ratio, trend to local buckling under the compression state, reducing the overall stability of components.
冷弯薄壁槽钢柱的板件宽厚比较大,在受压状态下容易发生局部屈曲而降低构件的整体稳定性。
Current HETs designed based on similarity theory have structure characteristics of narrow channel width, large volume, and high weight, which cause the structure is not sufficiently optimized and hence the overall thrust-weight ratio is small.
由于目前以相似理论为基础设计出的霍尔推力器普遍具有窄放电通道,大体积,高重量等结构特点,使得高功率霍尔推力器结构不够优化,整体推重比较小。
