摘　　要：针对装甲车辆柴油机在高原地区关键部件不能得到有效冷却导致柴油机故障频发,影响着装甲车辆的可靠性和作战效能发挥的问题,研究高原环境下柴油机冷却系统控制方案优化方法,提出了基于柴油机工况开环控制和基于柴油机出水口温度PID闭环反馈相结合的控制方法。最后以海拔5000m时为例编制了开环控制MAP图,对控制方案进行了模型仿真,结果表明优化后的控制系统能够有效提高冷却系统散热能力。Aiming at the problem that the key components of armored vehicle diesel engine can not be effectively cooled in plateau area,which leads to frequent diesel engine failures and affects the reliability and operational effectiveness of armored vehicles,the optimization method of control scheme of diesel engine cooling system in plateau environment is studied,A control method based on diesel engine open-loop control and PID closed-loop feedback is proposed.At last,an open-loop control map is drawn up when the altitude is 5000m,and the control scheme is simulated.The results show that the optimized control system can effectively improve the cooling capacity of the cooling system.
