为了进一步提高“弧焊电源”课程实验教学的效果,本文叙述采用微计算机辅助的实验教学形式。一、实验设计 1.微机辅助“电弧静特性曲线测定”实验按实测数据在方格纸上描点作图是这类实验中惯用的实验数据处理方法。由于电极形状、电网电压波动及读数误差等原因,实测数据总带有一定的误差,使实测数据与理论上U形曲线有偏差。在原电弧静特性测定实验中加入了用微机进行实验数据逼近处理的实验内容,要求在实测完成后带着实测
In order to further improve the experimental teaching effect of arc welding power supply, this paper describes the use of microcomputer-assisted experimental teaching. First, the experimental design 1. Microcomputer-assisted “arc static curve determination” experiment According to the measured data in the graph paper point drawing is the experimental experiment in these experiments data processing methods. Due to the electrode shape, voltage fluctuations and reading errors and other reasons, the measured data with a certain total error, the measured data and the theoretical U-shaped curve deviation. In the original arc static characteristics of the experiment added by the computer experimental data to approximate the experimental content of the experiment, requiring the actual measurement is completed with the measured
