为解决整机工况特征与液力变矩器选型的动力学匹配问题，提出面向液力变矩器定制化选型的积分加权评价法． 即在明确整机工况载荷特征的前提下，设定相应的变矩器速比区间 － 效率权重，通过对其效率特性曲线进行分段积分，加权得到积分加权评价值，并将其作为变矩器经济性能的评价标准． 文中分别以两个现有变矩器模型为选型对象，验证了提出的积分加权评价法对液力变矩器定制化选型的有效性． 该评价法可在简易地建立整机与配件匹配动力学映射关系的基础上，实现具有工程化意义的液力变矩器定制化选型．

In order to implement the dynamics matching between the working condition characteristics of vehicles and the type selection of hydraulic torque converters,an integral weighted evaluation method (IWEM) for the cus- tom-made type selection of torque converters is proposed.In this method,on the basis of the load characteristics of the vehicle,the speed ratio interval-efficiency weights of the torque converter are set correspondingly,the efficien- cy characteristic curve is segmented and integrated,and the corresponding integral weighted evaluation value is calculated and used as the evaluation standard of the economic performance of torque converters.Then,two exist- ing torque converter models are used as the objects to verify the effectiveness of the proposed IWEM for the custom- made type selection of torque converters.The results indicate that IWEM helps to set up the dynamic mapping rela- tionship between the vehicle and the accessories with ease.Thus,the custom-made type selection of hydraulic torque converters with engineering significance can be successfully implemented.
