(一) 前言转向架是机车的重要组成部分。它的性能和结构好坏,影响着机车平稳性和运行的安全可靠性。现代化机车的发展趋势是,随着功率和速度的不断提高,要求轻量化、有更好的粘着性能和优良的动力学品质,减少和方便维修、减少磨损件、增加各零部件的使用寿命。针对这些要求,近十几年来,国外研制了很多先进的转向架,有效地满足了高速机车牵引性能的要求。转向架悬挂装置的结构形式和参数合理匹配是机车动力学性能好坏的重要一环。客、货运机车转向架对悬挂装置的要求不
(A) Foreword Bogies are an important part of the locomotive. Its performance and structure is good or bad, affecting the locomotive stability and operational safety and reliability. The trend of modern locomotive development is that with the continuous improvement of power and speed, the requirements of lightweight, better adhesion performance and excellent dynamic quality, reduce and facilitate maintenance, reduce wear parts, and increase the service life of various parts. In response to these requirements, many advanced bogies have been developed abroad in recent ten years, effectively meeting the requirements of high-speed locomotive traction performance. The structural form of the bogie suspension and the reasonable matching of the parameters are the important links of locomotive dynamic performance. Passenger, freight locomotive bogie suspension requirements do not
