A vehicle dynamics behavior reproduction system capable of describing accurately behavior of a motor vehicle in a lateral direction even for nonlinear driving situation includes a vertical wheel force arithmetic means (105), a lateral wheel force arithmetic means (110), a cornering stiffness adaptation means (115), a state space model / observer unit (120), a selector (130), a delay means (135), and a tire side slip angle arithmetic means (125). Vertical wheel forces (FZij) and tire side slip angles (αij) are determined by using sensor information and estimated values while lateral wheel forces (FYij) are determined in accordance with a relatively simple nonlinear approximation equation. The lateral wheel force (FYij) and the tire side slip angle (αij) provide bases for adaptation of cornering stiffnesses at individual wheels. Vehicle motion is accurately described to a marginal stability by using adapted cornering stiffnesses (Cij) and other information.

When a vehicle approaches a corner, a microprocessor, responsive to a determination that a detected degree of roughness of the road surface corresponds to the most moderate roughness, sets the damping force for the vehicle suspension units, on the basis of the detected degree of roughness, vehicle speed and a radius of curvature and corner information from a navigation system. In the case of a determination that the detected degree of roughness does not correspond to the most moderate roughness, a damping level is set on the basis of the detected degree of roughness, vehicle speed and radius of curvature.

The invention discloses a railway vehicle body chassis structure. The railway vehicle body chassis structure soles the problems that the giant torque force is caused due to the fact that a front-arrangement type vehicle hook mounting hole is formed in the side face of a vertical plate of a traction beam, and no operation space exists for mounting a steering frame traction base. The railway vehicle body chassis structure comprises two chassis edge beams, a chassis end beam and a sleeper beam arranged between the two chassis edge beams, a traction beam, a vehicle hook mounting sectional material and a traction guide beam are arranged between the sleeper beam and the chassis end beam, the traction beam is fixed between the sleeper beam and the vehicle hook mounting sectional material, and the traction guide beam is fixed between the vehicle hook mounting sectional material and the chassis end beam. Traction wing plates are fixedly arranged on the two sides of the vehicle hook mounting sectional material, the traction wing plates are fixedly connected with the chassis edge beams on the corresponding sides, and a jumper box is arranged between the traction wing plates and the traction guide beam. The problems are completely solved by optimizing the structures of vehicle hook mounting sectional material, the traction beam and other components, and the high-intensity performance that a vehicle body can bear 1000 kN of compression loads is kept.

A rail road freight car truck has a truck bolster and a pair of side frames, the truck bolster being mounted transversely relative to the side frames. The mounting interface between the ends of the axles and the sideframe pedestals allows lateral rocking motion of the sideframes in the manner of a swing motion truck. The lateral swinging motion is combined with a longitudinal self steering capability. The self steering capability may be obtained by use of a longitudinally oriented rocker that may tend to permit resistance to deflection that is proportional to the weight carried across the interface. The truck may have auxiliary centering elements mounted in the pedestal seats, and those auxiliary centering elements may be made of resilient elastomeric material. The truck may also have friction dampers that have a disinclination to stick-slip behaviour. The friction dampers may be provided with brake linings, or similar features, on the face engaging the sideframe columns, on the slope face, or both. The friction dampers may operate to yield upward and downward friction forces that are not overly unequal. The friction dampers may be mounted in a four-cornered arrangement at each end of the truck bolster. The spring groups may include sub-groups of springs of different heights.
