摘要: 本文提出了應用非線性規劃方法設計鏟運機工作機構。首先分析了反轉六桿機構工作過程中的運動幾何關系,推導了運動方程和力學關系方程。確立了以機構平動性能和轉斗油缸最大出力為最小的雙目標函數,從而建立了約束非線性優化設計數學模型。
作者用所建立的數學模型,用SUMT優化方法,在高速電子計算機上,對國產ZLD-40型鏟運機工作機構進行了實例計算,驗證了數學模型及程序的正確性和可靠性,并取得了滿意的優化解。
計算結果表明:該機構選擇雙目標函數進行優化設計,較全面地提高了機構的設計質量和工作效益,這是常規設計所難以實現的。Abstract: In this paper, the method of nonlinear programming is used to design the Work-mechanism of scooper loaders. The mathematical model contains nine design variables, thirty-four constraint equations and one comprehensive objective function consisting of the parallelism of scoop upward motion and the rotating force of hydraulic cylinder for running scoop.
The above mathematical model had been applied for computation to the domestic ZLD-40 type scooper loader by means of SUMT and interesting re-sutls were obtained.
The computed resutls confirms the crrectness of the above mathematical model. The design quality and operation effectiveness of the work-mechanism pf the scooper loader could be improved by this method. -
