Vehicle travelling performance-based method for evaluating travelling service performance of highway bridge expansion device
The invention is applied to the field of highway bridge detection. If a bridge support or an expansion device is damaged, an expansion joint could be misplaced, and travelling vibration response may be caused under the stimulation of the concave-convex expansion joint. The invention discloses a vehicle travelling performance-based method for evaluating travelling service performance of a highway bridge expansion device. The method comprises the steps as follows: defining a travelling performance grading evaluation method and a travelling performance deterioration rate computing method; determining vehicle travelling performance according to a vehicle acceleration response signal, and determining a travelling deterioration rate according to an actual measured current value and a detection initial value of travelling performance; outputting an inspection and evaluation report according to a result of grading evaluation. By using the method for regularly tracking and monitoring vehicle travelling performance deterioration rate, the method of the invention can be used for diagnosing early damage of the evaluated object based on the travelling service performance. The method of the invention improves the recognizability of early damage of the highway bridge expansion device and support service and the quality of inspection and evaluation while improving detection efficiency.
