摘　　要：提出了履带车辆全电制动系统结构框图,设计了履带车辆单侧制动方案,搭建了系统试验平台。对制动器压紧力的计算进行了数学描述,提出了利用电流和丝杠位移这两种压紧力的估算方法,通过压紧力估算试验,拟合出压紧力与电流和丝杠位移的函数表达式,经力传感器验证后,得出利用丝杠位移来估算压紧力的方法更为准确、实用,可实现全电制动系统无力传感器的压紧力闭环控制。The structure diagram of the all electric brake system for military tracked vehicle was put forward,and its single side brake scheme was designed.The system test platform was built.The mathematical expression of the brake impaction force was illuminated.There are two ways to estimate the impaction force,by current and by screw position.Based on these,examinations were carried out to fit the polynomials of the impaction force about current and screw position,and then they were validated with force sensor.It can be concluded that it is exact and practical more to estimate impaction force by screw position,and it can be come true to control the impaction force in closed loop without force sensor.
