摘要
针对履带式装备铁路输送中加固耗时长、木材消耗量大、效率低,且不能有效解决装备连挂冲击惯性力引起的滑移等问题,需要设计出基于新型平车配有的加固装置,以此解决履带式装备平车输送的装载加固问题。首先,通过装载加固力学分析,揭示了履带式装备在平车输送时纵、横向的稳定性,由所建立的数学模型,求解出装备在满足必要约束时拉牵绳承受的载荷;然后,运用MATLAB编程仿真确定了拉牵加固在平车地板上的最优系固点;最后,通过优化计算揭示了拉牵绳拉力随系固点位置变化规律,给出了履带式装备装载加固时的最优拉牵角度。研究可为新型加固装置的设计提供理论参考。
In view of the problem that the reinforcement of the tracked equipment railway takes a long time,the wood consumption is large,the efficiency is low,and the slip caused by the impact inertial force of the equipment can not be effectively solved,the reinforcement device based on the new flat car need to be designed to solve the load reinforcement problem of the tracked equipment flat car transportation.Firstly,through the analysis of loading and reinforcement mechanics,the longitudinal and lateral stability of the tracked equipment on the flat car transportation is revealed.The mathematical model is used to solve the load that the equipment is subjected to when the equipment meets the necessary constraints.Then,MATLAB programming simulation is used to determine the optimal fastening point of pulling reinforcement on the flat car floor.Finally,the law of the tension of the pulling rope changing with the position of the fastening point is revealed through optimization calculation,and the optimal pulling angle of the crawler equipment during loading and strengthening is given,which can provide a theoretical reference for the design of the new type of reinforcement device.
