车辆-货物-约束系统侧翻失效力学特性的研究

摘要

建立了车辆-货物-约束系统的力学模型,采用侧向加速度作为车辆-货物-约束系统的侧翻指标,分析计算得到载货车辆的侧翻临界值.在该翻临界值的基础上,建立货物-约束器模型,分析货物不发生倾翻和滑移时所需约束器的数量.%The paper uses lateral acceleration as vehicle-cargo-restraint system rollover index, estab-lishses the model of vehicle-cargo-tie down system, analysises and calculates the rollover threshold. The model between cargo and constrained devices is builded based on the rollover threshold. The number of required tie is analysised while the cargo does not occur tipping and sliding. The research can provide theoretical basis for developing the using standard of constrained devices.
