摘要
针对自行式房车不同的空间布置方案引起整车行驶稳定性改变的问题,构建整车质心位置在水平和垂直方向变化最小的优化模型,并根据后轴荷与横向稳定系数对优化模型建立约束。结合萤火虫算法,用MATLAB编程求解计算,得到该方案内部设备质心的理想布置,从而提高了房车的行驶稳定性。
To solve the problem that the different space layout schemes of the self-propelled RV cause the variation of the vehicle′s driving stability,the optimization model with minimum centroid location changes in X and Z directions is established.According to the distribution of rear axle load and the lateral stability coefficient,the constraint condition is established for the optimization model.With the newly developed firefly algorithm and MATLAB programming,the optimal layout of the equipment is obtained,which improves the driving stability of the RV.
