Simulation Analysis Of Working Device Of Hydraulic Excavator Based On ADAMS

Hydraulic excavator is one of the most commonly used engineering machinery,it is mainly used in some large construction,infrastructure construction,and other aspects,however The design of hydraulic excavator's working device will directly affect its performance good or bad.Therefore,the simulation analysis and optimization of hydraulic excavator working devices are especially important.In this paper,it makes a hydraulic excavator with bucket capacity of0.55m~3 as the research object,based on 3D modeling software Solidworks and ADAMS software,it establishes Modeling,simulation and optimization of hydraulic excavator working device.First of all,Three-dimensional modeling of hydraulic excavator's components are established by using SolidWorks software,and assemble it by setting a constraint between relative parts.Then import the assembled model into ADAMS,the main parameters such as maximum excavation depth,maximum excavation radius and maximum excavation height of hydraulic excavator are obtained by kinematic analysis,by analyzing the force of each hinge point under different working conditions,we can get the optimal working state of hydraulic excavator under what working condition.Finally,an equivalent prototype,which is established in Adams,is used to optimize the ratio of the bucket mechanism of the hydraulic excavator,the ratio of the bucket bar mechanism and the lifting force of the boom,so as to obtain better working performance.Through practice,the virtual prototyping technology can be used to carry out a series of simulation analysis on the working device of hydraulic excavator,and can optimize it efficiently,greatly shorten the research and development cycle,save the research and development funds.
