Simulation and Optimization of the Tracked Chassis Performance of Electric Shovel Based on DEM-MBD
Powder Technology, 2021Abstract To study and optimize the tracked chassis performance of electric shovel performance. First, the sand-gravel pavement model is built based on the discrete element method (DEM), and the virtual prototype model of the electric shovel is established. On this basis, the impacts of the pre-tension force, the road-wheel spacing, the sprocket speed,

Finite Element Analysis on Chassis of Tracked Test Vehicle
2012 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring, 2012Chassis is one of the key components of tracked test vehicle. The strength and rigidity of chassis must be considered and structure resonance should be avoided during the process of structure design. The stress nephogram and strain nephogram of chassis are obtained, after static analysis in the finite element analysis software ANSYS. The maximum stress

Trajectory Tracking and Integrated Chassis Control for Obstacle Avoidance With Minimum Jerk
IEEE Transactions on Intelligent Transportation Systems, 2022Intelligent vehicles are expected to perform emergency lane change maneuvers to avoid a collision. During this aggressive maneuver, a high jerk may occur, which reduces the comfort level and may be harmful to vehicle occupants. The present paper addresses autonomous collision avoidance in the context of minimum jerk.

Vehicle path tracking by integrated chassis control
Journal of Central South University, 2015The control problem of trajectory based path following for passenger vehicles is studied. Comprehensive nonlinear vehicle model is utilized for simulation vehicle response during various maneuvers in MATLAB/Simulink. In order to follow desired path, a driver model is developed to enhance closed loop driver/vehicle model.

Multicaterpillar Track Chassis of Big Machines - Identification of Loads
Key Engineering Materials, 2011Multicaterpillar track chassis are used in the biggest machines. This kind of chassis is commonly used in open cast mines for mobile transfer conveyor or for bucket wheel excavators. In each machine the chassis consist of 6 to 12 caterpillar tracks, which some are steered.

Modular virtual assembly design of double-track power chassis
Proceedings of the 2013 International Conference on Advanced Mechatronic Systems, 2013In order to address the issues of low mechanization level and heavy labor intensity of manual film mulching and ridging in hilly and mountainous areas, a small double-track power chassis and relevant farming equipment are designed. Taking advantage of the top-down method and entity modeling in 3D (3-dimensional) design software Solidworks, a micro ...
