【摘要】：伸縮臂叉裝車是傳統(tǒng)叉車、輪式裝載機、高空作業(yè)平臺和小型汽車起重機有機結(jié)合而形成的一類新興產(chǎn)品,并逐步成為農(nóng)業(yè)、建筑、廠房建設(shè)等領(lǐng)域不可或缺的小型工程機械。它憑借工作裝置完成物料的裝卸、搬運和舉升,因此伸縮臂叉裝車工作裝置的結(jié)構(gòu)和性能參數(shù)直接影響整機作業(yè)性能。 本文以SWTH3514伸縮臂叉裝車工作裝置設(shè)計為例,應(yīng)用矢量方程解析法和牛頓-歐拉法建立伸縮臂叉裝車工作裝置多剛體運動學和動力學數(shù)學模型。利用計算機仿真技術(shù),在MATLAB-Simulink環(huán)境下,建立舉升作業(yè)工況下伸縮臂叉裝車工作裝置的多剛體動力學仿真模型,計算得到不同負載作用下工作裝置的動力學特性。在保證叉裝車工作裝置的舉升作業(yè)能力和卸料角一定的條件下,分別建立伸縮臂叉裝車工作裝置的變幅機構(gòu)、六連桿機構(gòu)以及平移性能的數(shù)學模型,采用遺傳算法多目標優(yōu)化方法,運用MATLAB優(yōu)化工具箱對數(shù)學模型進行求解,并對比分析優(yōu)化前后工作裝置的主要性能參數(shù)和動力學特性。以SWTH3514型伸縮臂叉裝車為實驗平臺進行相關(guān)實驗研究,驗證所建伸縮臂叉工作裝置動力學模型的正確性、仿真研究的可行性、優(yōu)化設(shè)計的有效性。
[Abstract]:Telescopic arm fork loading is a kind of new product which is formed by the organic combination of traditional forklift, wheeled loader, aerial working platform and small truck crane, and has gradually become agriculture and architecture. The construction of factory building and other fields is indispensable for small-scale construction machinery, which depends on the working device to complete the loading, unloading, handling and lifting of materials, so the structure and performance parameters of the working device of the telescopic arm fork loading vehicle have a direct impact on the performance of the whole machine. In this paper, taking the design of SWTH3514 telescopic arm fork loading device as an example, using vector equation analysis method and Newton-Euler method, a mathematical model of multi-rigid body kinematics and dynamics of the working device of telescopic arm fork loading vehicle is established, and the computer simulation technology is used. In the MATLAB-Simulink environment, the dynamic simulation model of multi-rigid body is established for the working device of telescopic arm fork loading under lifting operation condition. The dynamic characteristics of the working device under different loads are calculated. Under the condition of ensuring the lifting ability and unloading angle of the fork loading working device, the amplitude changing mechanism of the telescopic arm fork loading working device is established respectively. The mathematical model of the six-bar linkage mechanism and the translation performance is solved by using the genetic algorithm multi-objective optimization method and the MATLAB optimization toolbox. The main performance parameters and dynamic characteristics of the working device before and after the optimization are compared and analyzed. The dynamic model of the telescopic arm fork working device is verified by using SWTH3514 type telescopic arm fork loading as the experimental platform. The feasibility of simulation research and the effectiveness of optimization design.
