Chinas automotive market experienced rapid growth in the past several decades. The impact on the energy consumption and greenhouse gas(GHG)emissions become great concerns. In this study, a model based on life-cycle assessment(LCA)method- ology is established to estimate the GHG emissions caused by vehicle use in China from 2015 to 2050. Three scenarios are designed to de- scribe different penetration of electric vehicles and total vehicle sales. In these scenarios, the GHG emissions will separately decrease 34. 4%, 19. 8%, and 40. 9%in 2050 compared with that in 2015. The results indicate that the promotion of electric vehicles will effec- tively reduce the GHG emissions after 2035. Besides, the limitation of total sales of vehicles can also markedly reduce the emissions.

针对车辆怠速时驾驶座椅振动现象,对发动机悬置上下端及座椅导轨的振动加速度信号做阶次跟踪和频谱分析,认为该振动主要由发动机自身二阶激励引起.为消除该现象,将动刚度二级可变的空气弹簧式半主动控制液压悬置应用于发动机左侧支撑.试验对比表明,半主动控制的发动机悬置对怠速时发动机左侧的异常振动具有很好的隔离效果,提升了车辆怠速工况的振动舒适性,同时也满足了车辆正常行驶时的悬置动刚度要求.
