Abstract


Telescopic handler traditional forklifts, wheel loaders , aerial work platforms and small truck crane combine to form a class of emerging products and gradually become indispensable in the field of agriculture, construction , plant construction , small construction machinery . With the completion of the work unit material handling, handling and lifting , it telescopic boom forklift truck the structure and performance of the device parameters directly affect the performance of the whole job . The telescopic handler working device design to SWTH3514 for example , the application vector equation analytical method and Newton - Euler method to establish multi- rigid body kinematics and dynamics mathematical model of the telescopic handler working device . Use of computer simulation technology , MATLAB-Simulink environment , the establishment of lifting operating conditions telescopic handler device multi-rigid-body dynamics simulation model to calculate the dynamics of the work under different load device . Were established in certain conditions to ensure that the lifting of the forklift truck working device operating capacity and discharge angle , luffing telescopic handler working device , the mathematical model of the six -bar linkage and pan performance , using genetic algorithms objective optimization methods using MATLAB optimization toolbox to solve the mathematical model and comparative analysis of the device before and after optimization main performance parameters and dynamics . Experimental platform SWTH3514 type telescopic handler related experimental study , verify the correctness of the telescopic boom forklift device dynamics model built by simulation to study the feasibility , optimize the effectiveness of the design .
