Simulation Analyzed of Vehicle Operating Safety in Rain Weather Condition Based on ADAMS

摘要

The safety of vehicle operating has tight relation with the road condition; vehicle operating safety accident is easy occurred in badness road condition. This paper studied the vehicle Operating Safety in rain weather condition based on Multi-Rigid Body system Automatic Dynamic Analysis of Mechanical Systems (ADAMS). The models include Vehicle model, Road model, Vehicle and Road coupling model, Simulation module were set up. By changing road friction coefficient, road conditions in sunny day, dry, and rain weather were simulated. Single lane change text and ramp steering text were carried out, and the response output of lateral displacement was obtained. Computation result indicated that in the single lane change when road friction coefficient in rain weather is 0.4, vehicle speed is 60km/h in the single line simulation; the vehicle will be easily out of control. When vehicle speed is 55 km/h, maximum steer value is 70degree in the single lane simulation, vehicle will go haywire. In the ramp steer simulation when vehicle speed is 40 km/h, vehicle will go haywire.
