Abstract

The invention relates to a bench test method for evaluating the vibration comfort of an automobile seat, and belongs to the field of automobile seat vibration performance testing. The method comprises steps: establishing excitation source data of a vibration table through regression calculation of a real vehicle road test result of an automobile seat guide rail; acquiring bench test data of a tested seat; and calculating a seat vibration transmissibility and comfort comprehensive evaluation index. According to the method, a complete automobile seat bench test and evaluation process is established. Through a seat assembly rack vibration excitation test, vibration transmissibility and vibration acceleration root-mean-square values of the seat in the vertical and horizontal directions are obtained, a seat comfort comprehensive evaluation index GSS is further obtained, and the seat vibration comfort is evaluated by using the seat vibration transmissibility and the seat comfort comprehensive evaluation index. According to the method, in the early stage of vehicle development or the virtual development stage of a vehicle body, the vibration comfort of the seat of the supplier is recognized, the test period of model selection of the automobile seat is shortened, and the working efficiency is improved.

Description

Technical field: [0001] The invention belongs to the technical field of vibration performance testing of automobile seats, and relates to a bench test method for evaluating the vibration comfort of automobile seats. Background technique: [0002] The vibration comfort of car seats is one of the important indicators to measure the comfort of the occupants. The comfort of the vehicle seat is one of the most widely involved and most difficult problems in the control of performance parameters in seat performance. The invention aims to solve the problem of testing and evaluating the bench vibration comfort of the automobile seat assembly product. That is, how to determine the vibration comfort of the seat and what methods and indicators are used to evaluate the engineering technical issues. The purpose is to provide the basis and method for the vibration performance evaluation and selection of the vehicle seat in the process of vehicle product development. [0003] At present, t...
