基于STM32单片机的新型滚动尺

为解决传统直尺量程小、功能单一、携带麻烦等问题,文章设计了一种以STM32单片机为核心,使用增量式光电编码器采集数据并通过OLED显示屏实时显示和语音播报测量结果的新型滚动尺。该滚动尺具有量程大、精度高、使用方便等特点,不仅可以测量直线的距离,还可以测量曲线、曲面的距离。

成形磨齿砂轮修整器

目前,一般工厂使用最多的是机械式砂轮修整器,但它在结构上和功能上都存在一些问题.为此,设计了一种新型的渐开线砂轮形面修整器,它具有修整精度高、稳定性好以及修整砂轮的范围不受渐开线展开角的限制等优点.

Analysis of ink flow channel between two rotating ink rollers

In order to research how the size of the ink flow channel is affected by the interaction of adjacent ink areas,according to the method of fluid-solid interaction,this paper analyzes the size of the ink flow channel of two ink rollers' rotation.Firstly,this paper simulates the situation of only one ink area.Secondly,this paper simulates the situation of five adjacent ink areas.Then,through comparing the simulation results of two above situations,it' s obvious that the interaction of adjacent ink areas has big effects on the ink pressure and the size of ink flow channel.At last,this paper gets the main factor that affects the size of ink flow channel in the different situations.
