简介:基于沈阳鼓风机集团股份有限公司自主开发的转子动力学分析软件——RBSP_2012,对煤化工用10万m3/h空分压缩机组的复杂轴系进行扭转振动分析,获取24阶无阻尼扭转自然频率,绘制坎贝尔图,并结合振动能量分布对各个高、低速轴进行频率筛查,分析结果符合API617标准要求。
简介:换代后的X1即使用脱胎换骨来形容也并不过分.因为它确实较之老款有了实质性的飞跃,上一代X1是基于3系旅行版(E91)平台设计而成,在同属紧凑型SUV的ABB三驾马车中,已经属于一个敦实的小胖了.虽说全新换代后的UKL前驱平台和1.5T的三缸机让不少宝马死忠们嗤之以鼻.但不可否认的是,换代后越级的后排空间确实更符合国人的购车需求,只能说,宝马的设计师团队对于国人的用车诉求摸得相当透彻.
