궤도차량용 토크 컨버터 펌프의 형상 정밀도 측정을 통한 성능예측에 관한 연구

Abstract

To accurately predict the performance of the torque converter, the shape accuracy of the main component, thepump, was measured using a 3D laser scanning coordinate measuring machine (CMM). Products that met theconditions were tested with dedicated test equipment to determine the speed ratio representing the generalperformance of the torque converter. The torque increase ratio and capacity coefficient were obtained andcompared with the one-dimensional model-predicted performance to calculate the performance characteristics. The calculation results confirmed that if the shape of the pump satisfied the casting precision range of theproduction drawing, the performance characteristics were within the predicted range.
