Development of verification device for vehicle side slip test bench
In order to improve the verification efficiency of side slip test bench,an automatic verification device for side slip test bench which can realize dynamic displacement control and measurement was developed.Firstly,the system function of the verification device was analyzed,and the function of the device was defined.Secondly,the overall design was carried out,and the details of the three subsystems of mechanical mechanism,measurement and control system and human-computer interaction was analyzed.Thirdly,the mechanical mechanisms were designed and the components were adopted,and the key technical targets such as displacement control were realized.Then the controller was developed based on STM32.Finally,the calibration and performance test of the calibration device were carried out.The calibration results showed that the displacement measurement error was less than±0.01 mm and the force measurement error was less than 2%.Performance experiments showed that the static displacement control error was less than±0.01 mm.The dynamic displacement control error was not more than±0.1 mm.The developed verification device of vehicle side slip test bench can meet the requirements of verification regulations and realize automatic verification.
