| Abstract: | The car's body was modeled by the Euler-Bernoulli beam model,and the car's tires were modeled by the two springs with different spring index at both ends for the half-vehicle modal.The first two natural frequencies and model function of transverse vibration of moving vehicles over a smooth road were numerically solved.The transcendental equation and the eigenfunction were established by boundary condition based on the complex model function.The first two natural frequencies and the corresponding model funct... |
