Virtual-Prototyping Oriented Key Research and Development System of Load Haul Dump
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 assembly, main parameters verification and sub-system of LHD design, the new innovation design development system for LHD development is formed. A case study of a three cubic LHD design process is given, considering the multi-body dynamics oriented simulation of LHD overall performance ,the structure strength analysis and fatigue analysis of key components, mechanism optimization design and dynamic kinematics analysis of working device, stability, ergonomics and ROPS/FOPS (Roll-Over Protection System / Fall-Over Protection System) of driving cab, the satisfied design results is finally obtained.
