以牙轮钻机气控系统为例,计算了系统可靠度,并用动态规划对系统进行优化设计,即介绍一种液压气动系统可靠性优化设计方法。 Taking the pneumatic control system of a roller cone drill as an example, the reliability of the system is calculated and the system is optimized by dynamic programming. That is to say, an optimal design method for the reliability of a hydraulic pneumatic system is introduced.
