基于典型工况液力变矩器匹配性能的优化
Optimization of matching on torque converter with engine based on typical operating condition
摘要
Abstract
In order to avoid the deficiencies of matching between engine and torque converter, and reasonable matching between engine and hydraulic torque converter, some actual tests were performed under typical operating condition. After segmentation, mergence, filtration, elimination of abnormal value, the engine torque actually consumed by working pumps and auxiliary device was obtained on V shovel loading conditions. The evaluation method of the hydraulic torque converter and engine matching was established based on grey relational analysis method. With a hydraulic torque converter of ZL50 loader as an example, the effective diameter of circular circle on hydraulic torque converter was optimized in view of the shovel loading cycle condition. After optimization, the matching performance of engine and torque converter increases by 3.8%. The results show that the optimal matching scheme can be improved based on typical operating condition, which can provide reference for the proper matching between engine and hydraulic torque converter.关键词
