The vibration and impact of wiper reversal is one of the main factors causing the wiper's noise.In recent years,the kinematics and dynamics performances of wipers have been studied extensively.In order to study the vibration and impact characteristics of the wiper reversal process,a wiper reversal test bench based on translational test system was set up.Experiments and analyses about the vibration and impact characteristics of the wiper reversal process under different working conditions are carried out.The results show that,the wiper reversal test bench can realize the speed regulation function corresponding to each gear of the real vehicle,and the experimental results are basically consistent with the real vehicle test results.The test also can distinguish and simulate the different wet and dry conditions of the glass surface,and analyze the mechanical state of the blade.Within the range of the measurement working conditions,scrape speed and acceleration/deceleration of the wiper are positively correlated with the influence of vibration and impact.While comparing with the scrape speed,the acceleration and deceleration time has little effect on the vibration and impact during the reversal process of the blade.The experimental results have certain significance and value for further research on the mechanism and control of wiper noise.
