    Negative Temperature values due to friction between gears.

    Hello, I am trying to simulate temperature increase due to friction in a gearbox. I am performing this analysis in coupled field transient so that i can apply rotation and friction between the gears but the problem is, in the temperature result, minimum values are going in negative values...

    Modal analysis result interpretation

    Hello All, I am performing a modal analysis of a shaft in prestressed condition, now the result is that its safe upto 3 modes and after that stress and deflection are high. what is the meaning of these modes in actual working condition of my shaft? How do i know that shaft will reach upto...

    MAX DEFLECTION ALLOWED IN A MACHINE IN MODAL ANALYSIS.

    HELLO, I am performing modal analysis to find natural frequency and their deflection. What does these deflection values at different modes indicates? Also If modal testing is done on a machine constraining the base of the machine. How much deflection is allowed in such case?

    Strength of cold working steel

    Cold working is the process of plastic straining below the recrystallization temperature in the plastic region of the stress strain diagram. Properties of the material obtained from hot rolling are quite different from those obtained by cold working.  Consider the stress strain diagram of fig...

    Hello, I am doing a simple

    Hello, I am doing a simple shaft analysis qith only one step. I am applying convergence of 5%. The result is not getting converged if i apply fixed support. But if i apply displacement support it is converging successesfully. What is the reason?? Pls if anyone can help me with this...

    Non convergence

    Hello all, I am trying to do a convergence analysis. But there is an error coming A FAILURE OCCURED INSIDE THE MESH REFINEMENT MODULE. I tried many options but the solutuion does not get converged (i am getting result at the base mesh). What is this error about can anybody help me??

    Modesuperpoaition harmonic analysis

    Hello, I am doing harmonic analysis using MSUP. Here i am applying moment load in harmonic boundry condition but there is no effect of moment in the result. Changes in the value of moment doesnt make any change in the result. My model has a shaft with torque. Pls let me know what is...

    Magnetostatic analysis - Applying voltage on symmetric planes

    hello all, I am performing a magnetostatic analysis. It consists of vertical sticks of magnets inside the cylindrical case, there is a air gap between each magnetic stick, I want to apply a voltage difference on two vertical sides of stick but I suppose voltage difference can only be...

    confusion in unit of gravity

    hi..... I have this shaft fixed at one end and free at other end. I wanted to see the deflection of free end due to gravity. I am using SI system library for material (N/m2) (E= 2.1 x 10^11 , density= 7833) and applying gravity of 9.8 m/s2. but the deflection and stresses are coming very...

    Solid works to dwg translation problem

    Hi..... I am modeling a roll in solid works and making a drawing of it and then i translate it into a DWG file. The problem is the hyperbolic profile of the roll is not getting translate properly, the point are shifting little bit here and there and hence when the dwg profile data is machined...

    Spring element

    I am analysing a vessel and i can not fix it any where hence i am trying to put it on the few spring elements but the problem is, i am not able to apply proper value of stiffnes and hence the stress is coming very high and at the point of spring location. Pls if anyone can suggest me something.
