Simulation Techniques for Improving the Fuel Efficiency of Hydraulic Excavators

Simulation techniques to reduce the fuel consumption in hydraulic excavators are presented in three categories: first, a strongly non-linear dynamic simulation technique for a coupling system with a non-linear hydraulic system and a linkage system; second, a technique for evaluating fuel consumption in the engine when the engine powers the hydraulic pump in a digging operation performed by a hy...

Introduction of Product Introduction of PC200-8 Hybrid Hydraulic Excavators

A goal has been set to make a contribution to society in challenging global warming, especially to reduce the emissions of CO2, by developing a hybrid system that drives the swing device of a hydraulic excavator by electric drive, to significantly reduce fuel consumption. Reductions in emissions of greenhouse gases are not making satisfactory progress and regulation of the construction industry...

Coordinated and Force-Feedback Control of Hydraulic Excavators

The human interface of a Caterpillar 325FB fellerbuncher was modi ed to allow the operator to use (i) a 5-DOF joystick, and (ii) a 6-DOF magneticallylevitated joystick with sti ness feedback. While the operator commanded the velocity of the endpoint, an onboard computer system managed total system power, solved the inverse kinematics, servoed the joint actuators, and controlled the magnetically...

Hydraulic System Design and Dynamic Modeling of the Tire Roller

We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...
