摘要
对CRH2型动车组车体用Pro/Engineer进行车体三维实体建模。参考EN12663标准,并利用ANSYS模态分析法对其进行模态振动分析,分析结果表明车体结构是合理的且符合实际。根据典型的三种工况:空车状态、额定载荷状态、最大载荷状态的不同载荷,对车体结构进行仿真和分析,对车体底架的纵梁进行变截面尺寸优化以及强度优化设计,提出较合理的优化方案。
Use Pro/E to establish 3D model of CRH2 vehicle body. Taking standard EN12663 as reference, ANSYS modal analysis is used to analyze modal vibration. The results show the body structure is reasonable and realistic. According to three typical conditions including empty state, the rated load state and different loads under maxload state, the body structure is simu- lated and analyzed. The stringer variable-sectional size and strength design of the car body underframe are optimized, then a rea- sonable optimization scheme is proposed.
