J211-90型黄麻织机动载荷测试研究

A STUDY OF DYNAMIC LOADS ON MODEL J 211-90 JUTE LOOM

本文提供了J211-90型黄麻织机传给厂房的三维动载荷、动力矩测试方法和数据,并分析了影响三维动载荷的主要因素,最后研讨了经纱方向和铅垂方向载荷,并用自行设计的三维测力传感器,在国内首次测得J211-90型黄麻织机175r/min时的三维动载荷和动力矩的最大值为P_x=1800 N。P_y=9600 N,P_z=6000 N,M_x=5940 N.m,M_y=9200 N.m.这些数据是设计织造厂房的重要数据,也是织机设计中的重要参数。

This paper provides the method and the data of 3-dimensional dynamic loads and moments of force measured from Model J211-90 jute loom, and analyses the main factors affecting the 3-d dynamic load. Finally it discusses the loads in warp yarn direction and in vertical direction. The maximum 3-d dynamic loads and moments of forces on J211-90 jute loom at the speed of 175 r/min are P_x=1800N; P_y=9600N; P_z=6000N; M_x=5400N·m; M_y=9200N·m; These data are very important for building design and also for loom design.
