This file contains a scissor lift model with hydraulic actuation built using Simscape Multibody and Simscape Fluids. The scissor lift model is assembled from a library of parameterized component models. Intermediate models are included to show you the steps of modeling this system. A MATLAB UI is also included that allows you to interactively change the dimensions of the scissor lift.

Please read the README.txt file to get started.

helpful,powerful and extremely good for free.

Hello, when I downloaded and installed the files to my desktop. When I opened Scissor_Lift_Simscape_Multibody/Scissor_Lift_Simscape_Multibody/Scissor_Lift_R16a/Libraries/Scissor_Parts_Lib.slx on Mac, the library was opened but all the icons associated with the 10 blocks are missing. Instead, I got ??? on each block and 11 warnings listed below. Anybody knows what to do?

Steve, why you use 10 for link density in the param file?
