摘要
为进一步提升农用机械的辅助装置-空气压缩机的工作效率,完善农用机械的智能控制,选定型号OX-1. 6/10的空气压缩机进行参数优化分析。通过充分理解空气压缩机的工作原理及特点,确定了涡旋式空压机的核心部件参数变化范围,建立正确的数学理论模型,利用UG软件强大的三维建模与参数化二次开发功能,编制后台优化控制程序,获取空气压缩机定盘、动盘的物理模型,并融入目标函数与约束条件的计算关系,搭建测定空气压缩机外部性能参数的试验平台。组合参数变化试验表明:当涡盘的圆渐开线节距、涡旋圈的数目、背压位置角度等匹配合理,此时内部比功率获得最佳,相应的空气压缩机的排气量在保证基础条件前提下效率提高10%以上,可对相似空气压缩机的参数设计提供参考。
In order to further improve agricultural machinery equipment of auxiliary devices-the working efficiency of the air compressor and improve the intelligent control of agricultural machinery equipment,parameter optimization analysis was conducted for the air compressor with the selected model OX-1.6/10.By fully understanding the working principle and characteristics of air compressor,the parameter variation range of core components of vortex type air compressor is determined,and the correct mathematical model is established,then background optimization control program is compiled,using the powerful three-dimensional modeling and parameterized two development functions of UG software to obtain the fixing and dynamic physical model of the air compressor,and integrating the calculation relation between objective function and constraint conditions,the experimental platform for determining the external performance parameters of air compressor was built and tested by combination parameter variation.It was concluded that the optimal internal power can be obtained when the reasonable matching of vortex disk of circle involute pitch,vortex ring,back pressure position angle,etc.The corresponding exhaust volume of the air compressor would increase by more than 10%under the premise of guaranteeing the basic conditions,which could provide some reference for parameter design of similar air compressor.
