摘要
In a method and device for simulating properties of a fluid torque converter such as torque ratio, capacity factor and efficiency involving the execution of the steps of finding a plurality of parameters including a fluid passage angle and a fluid passage resistance from a vane profile of a vane wheel of a fluid torque converter, and simulating the properties of said fluid torque converter according to said parameters and an input and output torque relationship based on an angular momentum theory, said fluid passage angle is corrected according to a slip ratio between rotational speeds of input and output ends of the fluid torque converter for the purpose of accounting for the influences of the occurrence of flow separation. Good results can be obtained by correcting the outflow angle of a stator vane array by using a correction value given as a mathematical function of the slip ratio. Thus, the accuracy of simulation can be substantially improved with a minimum increase in the computer time.
