摘　　要：文章根据活塞式气动马达的结构和工作原理，推导出其单一的理论转矩解析式。这个解析式比现有的分段函数能更清楚地表达转矩的脉动规律，便于工程应用。其方法也适用于其他活塞数的气动马达或液压马达转矩的推导。Based on the structure and working principle, the mathematical expression of pulsating torque of an air motor with three pistons is derived in this paper,as pulsating torque is one of important motion performances of air motors. The result is better than the existing subsection functions,for it is more both clearly to express the pulsating torque law and easily to be used in engi-neering. The method is also can used for derivation of pulsating torque of air motors with different pistons and hydraulic motors.
