直接说结果的话，因为没做过这方面的实验，并不知道会产生怎么样的变化。文

If I say the result directly, because I haven't done any experiment in this area, I don't know what kind of changes will be made. <br>The seat part of the model proposed in the article is equivalent to the surface of a car seat. You only need to build a car seat model on the basis of this model, input the mass, damping and spring coefficient of the car seat, and calculate it through matlab. It is possible to obtain the predicted head transmission rate when there is a seat. One of the purposes of this research is to establish a more accurate human body model to predict the head transmission rate under different conditions. <br>According to previous studies, different sitting postures will have a certain impact on the vibration transmission of the human body. For example, the transmission rate of the head will also change to a certain degree when the position of the hand is different. However, the transmission method of human body vibration can still be described by the equation of the article. You only need to replace the changed human body measurement data, and perform parameter identification with the transfer rate obtained from the experiment, and then the parameters can be obtained.

Speaking directly about the results, I don't know what changes will happen because I haven't done any experiments in this field. In this paper, the seat part of the model is equivalent to the surface of the car seat. Only on the basis of this model, we need to build the car seat model, input the mass, damping and spring coefficient of the car seat part, and calculate by matlab, we can get the predicted head transmissibility when there is a seat. One of the purposes of this study is to establish a more accurate human body model to predict the head transmissibility in different situations. According to the previous research, different sitting positions have certain influence on the vibration transmission of human body, for example, the transmission rate of head will also change with different hand positions. However, the transmission mode of human vibration can still be described by the equation in this article. Only by replacing the changed anthropometric data and identifying the parameters with the experimental transmissibility, the parameters can be obtained.
