摘　　要：车辆运输是物流运输的重要组成部分,研究车辆运输过程中的货物响应对运输包装设计有着重要意义。考虑货物与车辆底板的耦合作用,建立十一自由度车辆-货物耦合模型,对比三向响应之间的关系,研究不同公路等级及货物相关结构参数(载荷量、刚度、阻尼)对系统响应的影响。结果表明:车辆货物耦合作用显著影响系统响应;运输中转动造成的影响不可忽略;载货量减小、刚度增大、阻尼减小,货物的振动响应随之增加;路况越差,货物及底板的振动响应越大。Vehicle transport is an important part of logistics transport.It is of great significance to study the response of cargoes in the process of vehicle transport.Considering the coupling effect between cargo and vehicle bottom,an 11-degree-of-freedom vehicle-cargo coupling model is established.The relationship between three-way response is compared,and the influence of different road levels and cargo-related parameters(load,stiffness,damping)on the system response is taken into consideration.The results show that the coupling effect of vehicle‐cargo significantly affects the system response.The influence of rotation in transportation cannot be ignored.The vibration response of cargo increases with a decrease of load,stiffness and damping.The worse the road condition is,the bigger the vibration response of cargo and vehicle bottom will be.The research results are of great significance and value for the design of vehicle-cargo transportation system.
