摘要
为真实反映半挂汽车列车弯道制动的运动特性,考虑载荷转移、鞍座、悬架和非线性轮胎等相关因素对车辆运动状态的影响,建立了适用MATLAB/Simulink的18自由度半挂汽车列车动力学仿真模型。通过实车试验验证了所建模型的可靠性,并进一步分析了半挂汽车列车鞍座位置、承载量、制动力分配和内外轮制动力差对车辆转弯制动时横向稳定性的影响。
A 18-DOF tractor-semitrailer nonlinear dynamics model was developed to describe the motion characteristics of tractorsemitrailer braking in a turn,considering the related factors on the vehicle such as load transfer,suspension,the saddle and tire.On this basis,it was calibrated that vehicle simulation model given by MATLAB/Simulink is reliable through real vehicle tests.It was further analyzed the effects on lateral stability such as saddle position,load,braking force distribution and inside/outside wheel braking force difference through simulation when tractor- semitrailer braking in a turn.
