摘要
换向机构是水平换向双向犁顺畅工作的关键,为实现换向方便、平稳,文章对水平换向双向犁的换向机构进行分析,推导出换向机构的结构参数h、∠BAD等与基础犁梁的角加速度、油缸活塞杆的推力之间的关系,建立了换向机构的数学模型;用C语言编程对上述参数进行优化设计;设计结果应用于1LB-240型水平换向双向犁上,检测表明设计结果合理、工作可靠,换向方便、平稳,达到了设计要求。该方法可应用于其它类似结构的优化设计。
The reversing mechanism is the key of reversal plough. In order to achieve the aim of convenient and smooth exchanging direction, this paper analyzed the reversing mechanism of reversal plough, deduced the relationship among parameter h, angle BAD and foundation girder's angle acceleration and the force of cylinder. The mathematic model of reversing mechanism was developed and C language was used to optimize the parameters. The design result was used to optimize 1LB-240 plough. The check and test show that the result of design is reasonable and exchanging direction is convenient and smooth. This method can be used to optimize the design of similar mechanisms.
