چکیده

In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. In order to operate energy-efficient the operator has to experience the machine as harmonic. This is important to consider during the development of such working machines.

Hybrid Power Systems for Construction Machinery: Aspects of System Design and Operability of Wheel Loaders

This paper will examine the wheel loader as a system with two parallel energy conversion systems that show a complex interaction with each other and with the power source. Using a systematic design approach, several principle design solutions for hybridization can be found. Furthermore, the human operator with his/her control actions needs to be considered as part of the total system. This pape...

A Methodology for Modeling the Influence of Construction Machinery Operators on Productivity and Fuel Consumption

This paper is concerned with modeling the actions of a human operator of construction machinery and integrating this operator model into a large, complex simulation model of the complete machine and its environment. Because human operators to a large degree affect how the machine is run, adaptive operator models are a necessity when the simulation goal is quantification and optimization of prod...

Dynamic Simulation of Construction Machinery: Towards an Operator Model

In dynamic simulation of complete wheel loaders, one interesting aspect, specific for the working task, is the momentary power distribution between drive train and hydraulics, which is balanced by the operator. This paper presents the initial results to a simulation model of a human operator. Rather than letting the operator model follow a pre-defined path with control inputs at given points, i...

Modeling and Optimal Control of 4 Wheel Steering Vehicle Using LQR and its Comparison with 2 Wheel Steering Vehicle

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

Control Effectiveness Comparison of Wheel Loader’s Longitudinal Vibrations by Means of Passive and Active Vibration Stabilisers

When wheel loaders move with velocity higher than 10 km/h, they are subject to intense longitudinal vibrations. These vibrations are experienced particularly unpleasantly by an operator. Passive vibration stabilisers are used for controlling their intensity. They make outrigger’s support more flexible so that outrigger’s vibrations counteract the wheel loader’s longitudinal oscillations when mo...
