Methodology for Prediction of Windscreen Wiping Area through Simulation 2017-26-0257

Front windscreen wiping test is legal requirement for all motor vehicles as per standards like IS15802:2008 [1], IS15804:2008 [2] in India. This test requires windscreen mock-up/actual vehicle to be tested along with all wiping mechanisms such that minimum percentage areas to be wiped should meet the requirements specified in the IS standard. From manufacturer’s perspective this involves investment of lot of time and cost to arrive at the final design solution in order to meet the wiping requirements. The work scope in this paper is limited to bus category of vehicles. The methodology presented in this paper would enable quick design solutions for bus body builders or manufacturers to meet the wiping requirements specified in IS standard. The methodology presented in this paper was developed to carry out windscreen wiping test through commercially available simulation software. This methodology was validated by correlating simulation results with the actual test results of widescreen wiping. Predicted results through simulation and experimentally measured values were found to be in close agreement. The complete methodology and the correlation results are presented in this paper. This methodology can be used in future for CAE based certification as an alternative for windscreen wiping area test.
