According to the development status of underground load-haul-dump vehicle (LHD) development, a virtual-prototyping oriented key research and development system of LHD is proposed. Based on the driven oriented and top-down design concept of virtual-prototyping, combining the overall performance design, multi-body system dynamics oriented characteristic analysis and simulation, machine …

Estimation of the center of gravity (CG) is the basis for intelligent control of the front-and-rear-axis-independent electric driving wheel loaders (FREWLs). This paper presents a novel real-time method for estimating the CG of FREWLs, which is suitable for driving and spading conditions on bumpy roads. A FREWL dynamical model is proposed to set up the state-space model.

Learn MoreVehicle dynamic analysis of wheel loaders with suspended axles . By Adam Rehnberg. Abstract. The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences

Results showed that (1) the three layouts of suspensions can greatly reduce the vector sum of weighted acceleration; (2) the UCS suspension affects both the driving and operation stability of the wheel loader, and the IC-R suspension affects the operation stability when the wheel loader scoops and unloads crushed rocks, (3) the IC-RP suspension with anti-roll and anti-pitch functions has little effect on the …

While suspended axles have great potential for improving ride comfort and performance, they will also necessarily affect the vehicle dynamic behaviour which is different in many aspects from that of passenger cars or other road vehicles: the wheel loader has a large pitch inertia compared to its mass, the axle loads vary considerably with loading condition, and the vehicle uses an articulated frame …

Jan 01, 2014 · Then a vehicle prototype model is built based on a specific wheel loader type and a tyre/terrain model. Finally, the prototype model and tyre/terrain model are imported to the multi-body dynamics analysis software-ADAMS to conduct a number of simulations using the stable angle-based instability threat indicator.

Nov 16, 2018 · Wheel loaders are engineering vehicles used for various tasks that require both hauling and excavating capacity. Unlike transportation vehicles, wheel loaders are built without any axle suspension, and dynamic loads from the ground on the cab are damped by their large diameter and soft tires, suspension seat, and elastic operator cabin mounts. 1,2 However, numerous field measurements …
Learn MoreThe traditional wheel loader is built without any axle suspension and experiences severe vibration. Three different layouts of hydropneumatic suspension, namely, unconnected strut (UCS), interconnected in roll plane (IC-R) and interconnected in roll and pitch plane (IC-RP), are installed on the wheel loader to improve ride comfort. This study mainly focuses on the damping effect of different
