Simulation Analysis of W-Beam and Highway Bus Based on ADAMS

In order to meet the highway safety requirements of the bus under different speeds, the model of highway bus and W-beam were established in UG software and the collision dynamics simulation was analyzed in ADAMS software. During a number of simulation experiments, the impact force and the lateral deformation displacements would be done through the W-beam was collided by the bus in different speeds. The result was proven to meet the regulatory requirements of the evaluation specification for highway safety barriers. The result show that: semi-rigid guardrail can be better deformation and guiding effect when the speed of bus was lower than 80 km/h, but when the speed was higher than 80 km/h, the collision avoidance effect of guardrail was poor and the bus was easy to cross the guardrail to case secondary accident.
