THE ANALYSIS METHOD OF THE MULTIBODY DYNAMICS SYSTEM USING PARALLEL PROCESSING

摘要

A method for analyzing an object dynamic mechanics system having multiple degree-of-freedom is provided to reduce analyzing time by disassembling the object mechanics system into a plurality of pieces and processing respective processes in parallel. A turnaround time of processes calculating Jacobian is computed for each entity. An intrinsic thread ID is given to each entity. A nonlinear motion equation of the object dynamic mechanics system is linearized through Jacobian computation by distributing the processes having the intrinsic thread to the threads in parallel according to the intrinsic thread ID. Jacobian of the motion equation of the system is converted into product of lower and top triangular matrixes with triangular matrix decomposition by distributing the processes of the part disassembling the motion equation of the linearized system to a plurality of threads generated in a CPU. A solution of the motion equation of the linearized system, which is converted through the triangular matrix decomposition, is output by distributing the processes of the part disassembling the linearized motion equation to the threads generated in the CPU.
