METHOD TO CONTROL MULTIBODY DYNAMICS APPLIED TO VEHICLE SIMULATOR

摘要

The present invention relates to a method to control multibody dynamics applied to a vehicle simulator and, more specifically, to a method to control multibody dynamics applied to a vehicle simulator, which calculates the magnitude of a three-axial translational acceleration of a vehicle by input of a geological element in a first operation or initialization of the simulator to determine a static state, and estimates and compensates horizontal and vertical acceleration components of the vehicle by a ground slope through vehicle mechanics, so as to realize initialization regardless of the posture of the vehicle. According to the present invention, the method to control multibody dynamics applied to a vehicle simulator comprises: a step (S11) of determining whether a multibody dynamics module should be initialized; a step (S12) of determining whether the ground to travel a vehicle thereon is a plane in a vehicle simulator when the initialization is required, so as to be branched to a step (S14); a step (S13) of estimating horizontal and vertical accelerations by a slope not in the case of the plane in the step S12; the step (S14) of calculating X/Y/Z directional accelerations generated in the vehicle in the vehicle simulator; a step (S15) of calculating the magnitude of an acceleration vector of the vehicle in the vehicle simulator; and a step (S16) of determining whether the magnetism of the acceleration calculated in the step S15 converges on zero to be branched to the step S14 when converging on zero and terminate a loop when not converging on zero.;COPYRIGHT KIPO 2018
