The invention provides a suspension system multi-body dynamics synergic simulated method and a system which relates to the simulated field of computers. The suspension system multi-body dynamics synergic simulated method and the system solves the problem that efficiency is low of a suspension system multi-body dynamics simulated design in the existing prior art. A combining way of a controlling and designing simulated platform and a multi-body dynamics simulated platform is adopted of the suspension system multi-body dynamics synergic simulated method and the system. Suspending displacement is fed back to the controlling and designing simulated platform by the multi-body dynamics platform based on the fact that a plurality of operating mode force of an operating mode force assembly invoked in sequence of the controlling and designing simulated platform are inputted to the multi-body dynamics simulated platform. Reactive force produced by suspending points is generated by the controlling and designing simulated platform and the reactive force is inputted to the multi-body dynamics platform to carry out simulated processing of the multi-body dynamics, thus synergic simulation is achieved. Due to the fact that based on the fact that the operating mode force of the operating mode force assembly invoked in sequence of the controlling and designing simulated platform, based on the fact that the synergic simulation is carried out on the controlling and designing simulated platform and the multi-body dynamics simulated platform, the efficiency of the suspension system multi-body dynamics simulated design is high.
Description
technical field [0001] The invention relates to the technical field of computer simulation, in particular to a multi-body dynamics collaborative simulation method and system for a suspension system. Background technique [0002] The suspension system is the connecting part between the powertrain system (including engine and transmission) and the frame, and its performance is directly related to the NVH performance of the vehicle. NVH refers to Noise (noise), Vibration (vibration) and Harshness (acoustic roughness). In terms of suspension performance research, multi-body dynamics software is currently used for modeling, and then different loads are designed for different working conditions. The modeling process is complicated, and the working condition force design is repeated many times, and the application process is time-consuming and laborious. , the design efficiency is low. [0003] It can be seen that the following problems exist in the prior art: the efficiency of m...
