    Problems with Fatigue Analysis

    Hey guys, I’m a mechanical engineer student and I participate in a project where I analysis the structure of a modern tricycle. I need help with the fatigue analysis. I make the training of fatigue by Altair and tried make the analysis, but I’m not sure of the results. I think the problem it’s on the TABFAT. About the TABFAT: My analysis has 1D and 2D elements. I obtained the following values in the Linear Static Analysis: Analysis 1D Analysis 2D σ_max 24,59 MPa 267,9 Mpa σ_min -19,71 MPa 0 MPa Can I represent the load cycle of my “vehicle” like a sinusoidal curve? Can you show me how I represent it? Should I represent these values for each of the fatigue analysis like one analysis for 1D elements and other analysis for 2D elements? Can I “mix” these values for the two analyses representing σ_max = 24,59 MPa and σ_min = -19,71 MPa? I think that a correct method is consider my load cycle like a variable load, but I don’t obtain experimental data. About the MATFAT: I acquired the MATFAT data by the eFatigue website, but I don’t obtain the SE (standard error of log(N)). How I find out this? If I consider SE like “Default” (zero), how will affect my analysis? Note: I’m making a SN analysis. Thanks for helping!
  2. Hello everyone I would like to do a thermo-mechanical optimization. The thermo-mechanical analysis is already done successfully. Now I was looking for a documentation or tutorial about this sort of topology optimization, but I could not find anything. Does anybody of you have a link or documentation to share, about thermo-mechanical topology optimizations? I thank you very much in advance!

    Use of dimensions in Evolve

    Hey guys I'm new to solidThinking Evolve and I need help about dimensioning my drawings. Can we give dimensions to our sketches like in CATIA or solidworks? Also, can we edit position of points according to dimensions? What are dynamic and static dimensions in evolve and how are they different? Please help. Thank you in advance☺️
  4. Hello guys, I wanna know how to create solid bodies in evolve using loft feature between curves. Actually I want to create spoke of wheel rim using loft command but I'm unable to make it a solid body. Do we get solid body if we loft between all the curves? Please help me regarding this. If you have any evolve model of rim spoke that will be very appreciable. Thank you in advance

    Load transfer

    Hi, I have ran a simulation of an assemble but the forces exerted on the model don't seem to tranfer on to other components. The components are connected through spotwelds. I have attached a picture that might explain the problem better. In the picture I have applied SPC BCs at the door hinge and latch. On the outer panel I then applied a high force along the nodes on the center line of the door. As you can see from the picture the forces on the outer panel don't transfer on to the likes of the impact beam. Could anyone advise me on what I should do to fix the problem? Thanks

    Impact analysis question!!

    Hi We are doing a car impact analysis against a pole (created as a rigid wall - Geometry type = cylinder). The simulation is running, but the impact only affects the front part of the car, it does't transmit the impact energy to the entire car. We think that we are missing to make a contact between the entire car, but we don´t know how to do it. As you can see in the second image, the front part of the frame, goes through the base of the car.

    Presentation of Hyperworks

    Hi Everyone ! i am a university student and i have one seacrhing project about Hyperworks. i wann ask Does somebody have one presentation or something like information includes what is this , how it works, how to use , what we can do with it ... İf somebody has and can send me I will be reall happy . Waiting your help Have a good day everyone
