    Miniature Scissor Lift

    Hi GregLocock, Exactly, that's all I need to know. Is there any miniature linear actuator that could fit in the aforementioned scissor mechanism and could provide such a force?

    Miniature Scissor Lift

    DustinScheu, I'm not asking about the equations that control the scissor mechanism, I'm asking about the possibility to find an actuator that could provide a relatively high force with small dimensions. Thank you.

    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...

    Locating a node in 3D assembly under ANSYS Workbench

    Dear Logesh, First of all, I would like to thank you for your valuable response. Concerning the rigid body motion, I'm doing a flexible dynamic analysis where all the bodies are defined with flexible behavior and connected through different joints. I'm obliged to constraint some degrees of...

    Fatigue data for piezoceramic material

    I have contacted the supplier who has said that they haven't such data. For Google, I've tried to found something useful but nothing has been found. Moreover, I have no access to this journal to obtain this article.

    Locating a node in 3D assembly under ANSYS Workbench

    Hi again, Seymours, After writing the input file and reading it in ANSYS Classic, how I could locate the node? In other words, what the commands for that? Elogesh, the stiffness behavior of all parts in my assembly is defined as flexible, what is the cause of this rigid body motion? Thank you

    Fatigue data for piezoceramic material

    Dear engineers, I'm doing a fatigue stress analysis on an assembly made of Piezoceramic material. So is it possible to tell me please where I could find the S-N curves for this material. I would be so grateful for any information you could share with me. Thank you in advance.

    Locating a node in 3D assembly under ANSYS Workbench

    Thank you Seymours for your reply. The problem is that I don't have ANSYS Classic. I would be so grateful for any further suggestion.

    Locating a node in 3D assembly under ANSYS Workbench

    Dear ANSYS users, Could anybody tell me how to locate a node in 3D model under ANSYS Workbench. I need that to know the soure of errors resulted from the flexible dynamic analysis on a 3D assembly. Please, find enclosed the error file resulted from my analysis. Thank you in advance, Chaabain

    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

    First of all, thank you for your replies. EdDanzer, the change of piezoelectric materials as a response of the applied voltage is too small - of the order 10e-3 mm. As I told before, the change must be between 5 and 10 mm.
