Response Statistics of a Shape Memory Alloy Oscillator with Random Excitation
Round 1
Reviewer 1 Report
the article has some typos that make it difficult to understand. For example. line 10, line 37....
Citations of other papers should be changed, sometimes authors write "Spanos et al." and sometimes "Shang and Wang" should acquire the scientific writing form.
The last paragraph of the introduction should be removed, in this paragraph, an overview of the paper can be introduced but not in this form.
The article doesn't follow the typical scientific paper structure.
the title says "...shape memory alloy..." but in the paper, I see nothing about the alloy, is it a novel alloy? or is it a commercial alloy? why was this alloy chosen for investigation?

Responses to the Reviewer #1’s comments:
Comment #1: The article has some typos that make it difficult to understand. For example. line 10, line 37....
Response: Thank you for your careful comments. Some typos have been corrected in the revised paper to make it easily understand.
Comment #2: Citations of other papers should be changed, sometimes authors write “Spanos et al.” and sometimes “Shang and Wang” should acquire the scientific writing form.
Response: We have changed and unified the style of all the citations in the revised version to meet the scientific writing form.
Comment #3: The last paragraph of the introduction should be removed, in this paragraph, an overview of the paper can be introduced but not in this form.
Response: Thank you for your kind comments. We have corrected the last paragraph of the Introduction, and hope that the revised manuscript can meet your requirements.
Comment #4: The article doesn’t follow the typical scientific paper structure.
Response: We have referred a lot of literature and checked our manuscript carefully, and some changes have been made in the revised paper. Now we believe that our paper strongly follow the scientific paper structure. Thank you.
Comment #5: The title says “...shape memory alloy...” but in the paper, I see nothing about the alloy, is it a novel alloy? or is it a commercial alloy? why was this alloy chosen for investigation?
Response: Shape memory alloys (SMAs) belong to a class of shape memory materials, which have the ability to ‘memorise’ or retain their previous form when subjected to certain stimulus such as thermomechanical or magnetic variations. The source of the distinctive mechanical behavior of these materials is a crystalline phase transformation between a high symmetry, highly ordered parent phase (austenite), and a low symmetry, less ordered product phase (martensite). SMAs present high reversible strains compared to the conventional materials (pseudoelasticity) and permanent deformations that disappear upon an increase in temperature (shape memory effect). Due to this unique mechanical properties, SMAs have been manufactured into intelligent and parameter-controllable components for deformation and vibration control of engineering structures and mechanical equipment. SMAs have drawn significant attention and interest in recent years in a broad range of commercial applications, due to their unique and superior properties. More details can refer to the review article [1]. So, we chose this alloy for investigation in our study, and attempt to explore the nonlinear stochastic dynamics of the SMAs that operating in random environment.

Reviewer 2 Report
A brief summary
The theoretical model of a spring made of shape memory alloy (SMA), which has one degree of freedom and is under the influence of narrow-band random excitation, was investigated. A multiscale method was used for the theoretical analysis of the SMA oscillator. It was shown that the obtained approximate analytical solution of the model dynamics is in good agreement with the numerical results for both in deterministic and stochastic case. Stochastic switching and bifurcations were observed with changes in temperature and noise intensity. The study of the influence of random disturbances on the evolution of the dynamic behavior of the system is of great practical importance for the safe and reliable operation of the oscillatory system SMA.
Broad comments
In a number of places, the manuscript gives the impression of a draft. For example, most references are not numbered in the Introduction. I cannot verify the correctness of all the mathematical formulas presented, but I am afraid that a thorough check of the text should concern not only the references in the Introduction. The text of the manuscript should be carefully checked by the authors.

Response: Thank you for you kind comments. The numbers of all references have been added in the Introduction. We have checked the whole manuscript carefully and made some revisions in the revised version. We hope that the revised manuscript can meet your requirements.
Reviewer 3 Report
In the presented article there is a repeated error of the literary reference in the lines: 37, 40, 42, 45, 46, 57, 58, 61, 70, 151. It is necessary to correct it. The presented article is very interesting and apart from the error of the literary source I have no reservations. But I must point out that it is intended for a narrower group of readers who are engaged in a nonlinear dynamic system with a link to synergetics.
