摘要 为实现履带式自行火炮转向过程的自动控制,满足无人驾驶的功能需求,其零差速式双流传动装置中的静液转向系统需要进行无人化自动控制改造。综合考虑火炮双流传动特性对于自身转向过程的影响,针对系统的火炮转向半径R由转向控制电流I、车速v、发动机转速ne、马达输出转速nm(反馈控制)和直驶流转速n等参数共同决定,确定了自行火炮无人转向控制的指令输入,然后根据仿真模型分析得到的转向控制电流与期望转向半径、直驶特性参数的控制关系,制定了实现车辆的转向控制策略和方法,并对上述方法进行仿真验证。 For a tracked self-propelled gun with split path transmission system to achieve unmanned steering control,firstly it is required to considers the influence by unmanned vehicle characteristic and the split path transmission performance.And a conclusion is drawn,which means that stee-ring radius of the tracked self-propelled gun is determined by the steering control current,the straight speed,the engine speed,the motor output speed(feedback control)and the transmission output.Then accor-ding to the relationship of steering control current,expected steering radius and straight-line running movement characteristic parameters,a control strategy and method was put forward,with the above method simulated and verified.
