摘要：

为了定量评价液力变矩器与发动机匹配方案的合理性,根据理想匹配原则制定了无量纲的匹配评价指标,并提出了一种指标标准化评分方法。考虑了各评价指标在不同应用场合下重要性的差异,采用层次分析法确定出各评价指标的相对权重。基于改进雷达图法,建立了由匹配评价向量和匹配评价函数组成的液力变矩器与发动机匹配评价体系。以满足动力型匹配需求为例,对3组液力变矩器的共16种匹配方案进行了定量评价。结果表明:采用该方法可以准确、直观地选择出符合需要的最优匹配方案。

关键词: 液力变矩器, 变矩器匹配, 改进雷达图法, 层次分析法

Abstract:

In order to quantitatively evaluate the rationality of matching scheme between engine and torque converter, a series of dimensionless matching evaluation indexes were developed according to the ideal matching principle, and a standardized scoring method for every index was put forward. Considering the differences of importance of the evaluation indexes in different applications, relative weights of each index was determined using analytic hierarchy process. A matching evaluation system consisting of matching evaluation vector and matching evaluation function was established based on an improved radar chart method. Taking the powered matching demand as an example, three groups of hydrodynamic torque converters for a total of sixteen matching schemes were quantitatively evaluated. Evaluation results show that, using the proposed method, the optimal matching scheme can be determined accurately.

Key words: hydrodynamic torque converter, torque converter matching, improved radar chart method, analytic hierarchy process
