摘要
为研究车辆间纵向冲动对平稳性和舒适度指标的影响,建立了动车组连挂模型,并通过联合仿真技术对动力学模型施加牵引、制动与基本运行阻力。分析结果表明纵向作用力对车辆舒适性存在不可忽略的影响,由于纵向力的作用,纵向舒适度指标在计算中最大升高了200.75%,而平稳性指数则无法体现纵向力对车辆运行品质的影响。
To research the influence of longitudinal impact on stability and comfort index, coupled EMUs model was built, and traction force, braking force and basic resistance were applied to the dynamic model by co-simulation for simulating the EMUs longitudinal impact. Results showed that： influence of longitudinal force on the comfort could not be ignored, and because of longitudinal force, longitudinal comfort index increased by 200.75% maximum, stability index could not reflect the influence of longitudinal force on EMUs operation quality.
