基于ADAMS的公路大件货物运输仿真及绑扎加固分析

为了有效地分析大件货物在运输过程中的安全性，利用ADAMS建立公路大件货物运输整车模型，针对随机路面设置不同运输工况，分析车辆行驶速度及货物重量对货物振动加速度的影响情况，利用MATLAB生成加速度均方根值拟合曲面，得出货物振动加速度随车辆行驶速度和货物重量变化的曲面拟合公式，最后通过拟合公式对某大件货物运输案例进行安全绑扎校核。研究结果验证了曲面拟合公式的可行性，可为公路大件货物绑扎加固校核提供理论依据。

Simulation of Highway Bulk Cargo Transportation and Analysis of Binding and Strengthening Based on ADAMS

In order to effectively analyze the safety of bulk cargo in the process of transportation, ADAMS was used to establish the complete vehicle model of highway bulk cargo transportation. Different transportation conditions were set on random road surface. The effects of vehicle speed and cargo weight on cargo vibration acceleration were analyzed, and the relevant data were obtained. MATLAB was used to generate the root-mean-square value fitting surface of acceleration data, and the curved surface fitting formula of cargo vibration acceleration varying with vehicle travel speed and cargo weight was obtained. Finally, this formula was applied to the actual binding and reinforcement cases. The results show that the surface fitting formula is feasible and can provide a theoretical basis for the check of highway bulk cargo binding.
