摘要
介绍了自由活塞式斯特林发动机(FPSE)中的3处间隙密封以及间隙密封所产生的损失。根据理论公式计算,总结分析了变径配气活塞热端径向间隙、冷端径向间隙以及长度比对泵气损失、穿梭损失及总热损失的影响规律。
Three positions of clearance seals for free-piston Stirling engine （FPSE） were introduced and the losses caused by the clearance seal were listed. According to the theoretical formulas, the influence of seal at hot side and cold side and length ration of displacer with variable diameters on pump loss, shuttle loss and total heat loss were analyzed and summarized.
