Structural vibration performance test based on smart phone and improved comfort evaluation method

In view of the lack of portability and real-time performance of traditional instruments, the monitoring module based on smartphones which can achieve the acquisition of structural acceleration is developed. The accuracy and performance of smart phone through dynamic test is verified. Aiming at the shortcomings of the comfort evaluation method in the scope of application and evaluation parameters, the idea of displacement and velocity limits is put forward, and the evaluation limits applicable to different structures are given. The results show that the limits of displacement and velocity can be used as supplementary indexes for comfort evaluation of flexible structures.
