Performance evaluation and numerical simulation for non-linear dynamic suspension system of vehicles |
| |
| Abstract: | Runge-Kutta method is used in solving second-order differential equations for simulating a non-linear vehicle dynamic system of five freedoms. Numerical simulations are carried out for effective linear and non-linear dynamic systems simplified from certain vehicles. It shows that effective linear simplification for non-linear dynamic system produces error for vehicle evaluation. For modern vehicle suspension systems with non-linear springs and shock absorbers, non-linear numerical simulation is effective. The performance evaluation and numerical simulation software for the dynamic system of non-linear suspension developed by authors are also introduced. |
