摘要
结合虚拟样机技术和控制系统仿真技术对自行式重载运输车的自动调平系统进行了设计研究,建立了运输车横向半车多刚体动力学模型,并针对该模型设计了模糊控制器。联合仿真研究结果表明,模糊控制策略能对车架横向倾斜有很好的控制效果。调平精度达到0.17°,调节时间约为1.6s,能够满足调平系统高精度和快速度的要求。
Connected virtual prototyping technology and control system simulation technology, this paper study for the automatic leveling control system of heavy transport vehicles.A horizontal semi-truck multi-body dynamics model has been built for the heavy transport vehicle, and a fuzzy controller has been designed for the model. The co-simulation results show that, fuzzy control strategy has a good control effect on side tumbling stability of vehicle. The leveling precision reached 0.17°, and adjusting time is about 1.6s. Higher accuracy and faster request of the leveling control system can be satisfied.
