基于土槽试验台的旋转耕作部件试验装置设计
Design of test device for rotary tiller components based on soil bin
摘要
Abstract
In order to meet the diversified testing requirements and to improve the interchangeability, generality and measurement accuracy, a test device was designed for rotary tillage components based on soil bin. The test bed structure design and the measurement system were introduced in the paper. The working principle of bridge system for strain measuring system was expounded emphatically. The working process and load variation of rollers were analyzed and the test indexes for load characteristic of working parts were designed. The MATLAB program was used and verified to collect the test signal and analyze the data. The results showed that the strain measuring system worked reliably and the linear factor was 1; the test device could effectually reflect the working load characteristic and meet the experimental requirements of rotary tillage components well.关键词
