Reviewer 2 Report

A typo in line 349 "for-aft". 

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

In abstract, there is no main conclusions. 

In section 2.3, only one subject is used to obtain the posture angles. Different percentile subjects have different angles. 

Figures 5-11 can be put into one figure to show all accelerations together. 

It is not clear how human-vehicle contacts are modeled.

The key drawback of this study is no validation.  

Reviewer 2 Report

The title of the manuscript is not clear at all. What do the authors mean by predicting frequency?  Abstract has also similar problem. e.g., I have never seen "dynamic automotive structure" at any literature. What do the authors mean?

 

From the manuscript, it reflect to mt that the authors are not familiar with the topic of human body modelling (parametric or non-parametric) and vibration. With all due respect to the authors, I suggest them to read the published articles in human body vibration and get familiar with this domain. It is not difficult to make a model and to see the responses of any segment of the model. The challenges of modelling is its verification and validation. 

Reviewer 3 Report

Figure 3 shows the terhraderal mesh and the text describes that hexahedral elements were used. Please describe in detail all the contacts used between the elements and the material models used. Please add the exact mechanical load system - shown in the diagram. 

There is a lack of in-depth analysis of the state of the art and comparison of results with other authors.

It should be noted that the values read in individual points are subject to high uncertainty.
