Seat vibration comfort testing method and device

Abstract

The invention discloses a seat vibration comfort testing method and device.A seat vibration comfort testing system adopted by the seat vibration comfort testing method comprises a to-be-tested seat and a data analysis platform, the to-be-tested seat is provided with an acceleration sensor, the acceleration sensor is connected with the data analysis platform, and the data analysis platform is connected with the acceleration sensor. The method is applied to the data analysis platform and comprises the steps that after a user sits on the to-be-tested seat, the to-be-tested seat vibrates according to a plurality of sets of preset excitation signals in different directions, each set of excitation signals corresponds to an excitation acceleration, and for each set of excitation signals, each set of excitation acceleration corresponds to a set of excitation acceleration; and acquiring a vibration acceleration corresponding to the following vibration of the to-be-tested seat under the excitation signal, calculating the vibration transmissibility of the to-be-tested seat according to the vibration acceleration and the excitation acceleration, and generating a comfort test result according to a plurality of vibration transmissibility calculated under the plurality of groups of excitation signals in different directions.

Description

technical field [0001] The present application relates to the field of automotive engineering, and in particular, to a method and device for testing seat vibration comfort. Background technique [0002] As an important part of the car interior, the car seat is a system engineering product integrating ergonomics, mechanical vibration, mechanical analysis, and control engineering. With the development of automobile technology and the improvement of people's living standards, the comfort of car seats has become an important criterion when people choose a car. [0003] The comfort of car seats mainly includes static comfort and dynamic comfort. When researching the dynamic comfort of car seats, it is particularly important to test the dynamic comfort performance of car seats. It is only through the combination of simple seat vibration data and human subjective feelings to determine whether the seat meets the requirements of dynamic comfort, without testing the shock resistance ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the embodiment of the present application is to solve the problem that the existing test method does not detect the anti-seismic performance of the seat, and the current detection of the dynamic comfort of the car seat is a test under a single vibration direction, and in the actual use process , the vibration direction of the car seat is not single, so it is impossible to test the dynamic comfort of the seat more accurately
