本文讨论了起道机的优化设计问题,在满足电气化铁路对起道机使用安全,操作方便等要求以及对原机基本结构不作大变动的前提下,以操作力大小作为目标,建立数学模型,进行优化设计,优化后起道机操作力比原机操作力减小41.2％,结果经过实测验证,被厂方采用。 In this paper, the optimization design of the hoist is discussed. Under the premise of meeting the requirements of the electrified railway on hoist safety and ease of operation, and not changing the basic structure of the hoist greatly, taking the operating force as the goal, a mathematical model is established, Optimize the design, the optimized lift operation force is 41.2% less than the original machine operation force. The result is verified by the factory and adopted by the factory.
