Spatial Kinematics Modeling and Simulation of Wheel Loader
The wheel loader is modeled as a mechanical manipulator with four degrees of freedom (DOFs), which comprises a seven-bar linkage using the symbolic notation of Denavit and Hartenberg. Homogeneous transformation matrices are used to capture the spatial configuration between adjacent links. The forward kinematics method is used to formulate the kinematics equations by attaching Cartesian coordina...
متن کاملThe Analysis of Wheel Loader Diesel Engine Crankshaft Failure
The main purpose of this study is to review the cause for the crankshaft failure of six-cylinder diesel engine of a wheel loader after passing a short period of time. The failure had occurred after 4800 hours of in-service in the fifth crankpin of the crankshaft. Hardness and tensile tests were carried out to study their mechanical properties. Spectrophotometer machine was used to examine the c...
متن کاملOptimal Predictive Control of Wheel Loader Transmissions
The transmissions of present heavy wheel loaders are in general based on torque converters. The characteristics of this component suits these machines, especially in that it enables thrust from zero vehicle speed without risk of stalling the engine, without active control. Unfortunately, the component also causes losses which might become large compared to the transmitted power. One approach fo...
متن کاملAutonomous Scooping of a Rock Pile by a Wheel Loader Using Disturbance Observer
A controller for a miniature wheel loader is developed to scoop rock piles autonomously. During a scooping task operation, the load of the bucket varies momentarily according to the phase of scooping. Before the insertion of the bucket into the rock pile, the load is just the bucket weight, but after the insertion the reaction force from the rock piles is applied to the bucket. The values of th...
متن کاملIntroduction of Product Introduction of Large Wheel Loader WA600-6
Since it was introduced to its market in 1995, the WA600-3 has won a high reputation among users in various fields. However, more than ten years have passed since the last model changes and a review has become necessary reflecting changes in user needs and model changes of competing machines. Activities have been undertaken to meet social regulations such as Tier-3 exhaust gas regulation to be ...
