Abstract
Taking the steering block of mine shuttle car as the research object, a three-dimensional solid model of the steering block of mine shuttle car is established by SolidWorks. Based on ANSYS Workbench, the total deformation and stress of the steering block of Mine shuttle car under tension are obtained. According to the boundary conditions, the steering block is optimized by topology optimization, and the steering block is optimized by the results of topology optimization, and finally verified by static analysis. The results show that the mass of the optimized steering block is reduced by 11.7%. This study provides a reference for comprehensive performance analysis and optimization of Mine shuttle car steering block.
Highlights
Mine shuttle car, as a trackless rubber-wheel vehicle for short-wall mechanized mining, is a coal mine auxiliary transportation system towed by wire ropes
Through the three-dimensional modeling of steering block structure, the stress variation of steering block is analyzed and the ideal state is obtained by combining the topology optimization module
Force is the pull of steering cylinder to steering block; Force 1 is the resistance of longitudinal tie rod to steering block; Force 2 is the resistance of soft shaft to steering block
Summary
As a trackless rubber-wheel vehicle for short-wall mechanized mining, is a coal mine auxiliary transportation system towed by wire ropes. Its main function is to transfer coal from continuous coal miner to feed crusher. It is suitable for rail transportation with long distance, large inclination, variable slope and large tonnage, featuring flexibility, simple structure and large volume. The road under the working condition of mine shuttle car is relatively narrow and restricted by space, so the steering mechanism of mine shuttle car should be controlled sensitively. Through the three-dimensional modeling of steering block structure, the stress variation of steering block is analyzed and the ideal state is obtained by combining the topology optimization module.
