    Longevity of piezoceramic generator

    Dear all, I would like to know if it's possible to calculate the longevity of piezoceramic generator given that the applied time-varying load is known. In other words, could we calculate how many cycles of time-varying load the piezoceramic element can support before failure. Is there any...

    A question about fatigue analysis using ANSYS Workbench

    I am performing a fatigue analysis for the mechanism shown in Figure 01. This mechanism is made of titanium alloy (Ti-6AL-4V). It’s supposed to be locked at this position. After being locked, each of the two upper plates should support till 5E6 cycles of the time-varying load shown in Figure 02...

    Error message in ANSYS Workbench 11

    Dear all, I'm doing a flexible dynamic analysis of an assembly imported from Solidworks to ANSYS workbench 11. I've modified my model many times without being able to solve this problem: One or more elements have become highly distorted. Excessive distortion of elements is usually a symptom...

    Miniature Scissor Lift

    Dear all, I need to design a miniature electric scissor lift. Generally, it must be no larger than about 30 mm X 20 mm and a extended height of 10 mm. Minimum height is of a high importance and must be equal or less than (if possible) 5 mm. This lift must fold. Therefore, a screw actuator is...

    Analyzing Nonlinear Contact Using ANSYS Workbench?

    Dear all ANSYS Workbench Users, I am performing a flexible dynamic analysis on an assembly with moving parts using ANSYS Workbench. As you know in this case,the contact area between components changes during the load history. I need to obtain the contact area for some points of load history...

    Suggested distractor mechanism, any help?

    Dear all mechanical engineers, I have a problem and I would like to know if you can help me to get a solution: Our system consists of a fixed plate, a mechanism, and a mobile plate. When the force applied to the mobile plate is equal to Fa =150 N, the mobile plate is stable (Case 1). As this...

    Type of elements in ANSYS Solidworks

    Dear all, I would like to know what type of element has been used after meshing the assembly using ANSYS Workbench. In the details of mesh, I couldn't find the type of element. In other words, how could I mesh my assembly by 8-node-hexahedron elements? Thank you in advance Chaabain

    Biosensors

    Hello everybody, I would like to know if there is a miniature force sensor (Height < 5 mm ) which could be implanted in the human body for more than 15 years without any problem of calibration. These sensors have to measure forces that could reach 3000 Newton. I'm wondering if piezoelectric...

    Import Solidworks part to ANSYS using IGS

    Hello everybody: I have to import a solid piece from Solidworks to ANSYS to study it using FEA. I have saved this piece as igs file (With good options: "IGES solid/surface entities" is Trimmed surface - type 144). When I try to import this file to ANSYS, it does’nt work and I get the following...
