为分析车体弹性对大客车平顺性的影响,本文运用模态理论、能量迭加原理及模态参数识别技术,建立了计及车体弹性的“刚-弹”组合动力学模型.通过计算机模拟,分析了车体弹性对整车传递特性的影响.
In order to analyze the influence of vehicle body elasticity on the ride comfort of the bus, this paper establishes the “rigid-elastic” combination dynamics model which takes into account the elasticity of the vehicle body by using the modal theory, energy superposition principle and modal parameter identification technology. Simulation and analysis of the impact of vehicle body elasticity on the transmission characteristics of the vehicle.
