【摘要】：铰接转向机构是铰接车重要组成部分之一,既对整车的动力性、转向稳定性产生重要影响,也是整车安全运行的重要影响因素。以油缸铰接点位置为变量,建立铰接转向机构优化设计数学模型,分析变量对转向过程系统消耗的平均功率、最大转向角和最大行程差等几项动态性能指标的影响。分析数据表明,铰接点位置对平均功率和最大行程差影响较大。在此基础上以转向过程的最大行程差和平均功率为目标函数,在一定的约束条件下,包括边界条件约束、油缸结构尺寸约束、伸缩比和传力角度约束等,对转向机构进行了优化,优化后改变了油缸铰接点位置,并使最大行程差减少39.55%,消耗的平均功率减少4.99%。
[Abstract]:Hinge steering mechanism is one of the important parts of articulated vehicle, which not only has an important influence on the vehicle's power performance and steering stability, but also plays an important role in the safe operation of the whole vehicle. A mathematical model for optimal design of hinged steering mechanism is established with the position of the hinge point of the cylinder as the variable. The influence of the variables on the dynamic performance indexes such as the average power consumption, the maximum steering angle and the maximum stroke difference of the steering process system are analyzed. The results show that the position of hinge point has great influence on average power and maximum stroke difference. On this basis, the maximum stroke difference and the average power of the steering process are taken as the objective functions. Under certain constraints, including the boundary constraints, the cylinder structure size constraints, the telescopic ratio and the transmission angle constraints, etc. The steering mechanism is optimized, the position of the hinge point of the cylinder is changed after the optimization, and the maximum stroke difference is reduced by 39.55 and the average power consumed is reduced by 4.99.
