ABSTRACT

In order to comprehensively evaluate the performance of matching between engine and torque converter, a series of matching evaluation indexes were developed according to the ideal matching principle and a standardized treatment for every index was put forward. Considering the different importance of each indexes in different applications, weight of each index was given by using comprehensive method, The evaluation method of the hydraulic torque converter and engine matching was established based on the improved radar map method. The objective function was constructed based on the sum of each evaluation index and the perimeter of radar map. 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. The original size of torque converter effective diameter was 0.340 m. After optimization, the effective diameter of hydraulic torque converter was 0.350 m, and the matching performance of engine and torque converter was increased by 7.4%. The results show that the optimal matching scheme can be improved by using the improved radar map method.
