The Structural Refinement and Vibration Analysis of Apparatus Based on Inertia Benchmark for Measuring Road Roughness

Abstract:

The Apparatus for measuring road roughness based on inertia benchmark are usually used with method of “calculation amendment”. The exquisite vibration of sprung mass and double integration of acceleration can bring error to measuring result. The amelioration was took to this kind of device by adding a mass block called measuring benchmark. Vibration characteristic was analyzed through vibration equation. To reduce the error, the perfect combination of system parameters was found to minish the amplitude of measuring benchmark. The analysis indicated that when selecting appropriate system parameters the dimensionless amplitude can be tend to “1”.
