Simulation and optimization of hydraulic excavator?¢????s working device based on MATLAB


The kinematic and dynamic analysis of hydraulic excavator’s working device was carried out in this paper by using the De-navit-Hartenberg homogeneous transformed matrix. And then we worked out the optimization results of comprehensive characteristics for kinematic and dynamics based on using the max digging power as the aim of optimization. It established the theoretic foundation for further study in order to realize the hydraulic excavator’s automatic control. Finally take the type of YC225LC-8 hydraulic backhoe excavator for example, simulation and optimization analysis of it’s comprehensive characteristics. The research results showed that the method of C + + Builder and MATLAB mixed programming is make full use of MATLAB powerful scientific computing, as well as C + + Builder powerful interface development function. And the program development process is simple, high process efficiency and has reliable optimization results. It can find solid theoretical calculation foundation for further research on mining automatic. And it own the value of engineering application.
