本文综合描述了应用于液力变矩器性能试验的微机数据采集与处理系统(HTCCATS),阐述了该系统的组成原理和功能特点。文中提出了一种试验数据曲线拟合的实用方法——逐步搜索分段回归法。该方法已成功地用于HTCCATS中。
This article describes a microcomputer data acquisition and processing system (HTCCATS) applied to the performance test of torque converter, and expounds the composition principle and function characteristics of the system. In this paper, a practical method for curve fitting of experimental data is proposed - stepwise search subsection regression method. This method has been successfully used in HTCCATS.
