Using SolidWorks motion to examine loads

SolidWorks motion analysis has so many applications to offer and one of which is analysis of forces acting on members. In this scenario we will use SolidWorks motion to solve a simple statics problem.

Before we begin we need to activate the SolidWorks motion analysis add-in in the add-ins folder.

Next we will create a new assembly.

Considering the member shown below.

We will begin by creating a sketch representing the lines of action of the forces.

After defining the sketch it’s time to run a new motion study.

For the member 30 degrees from the vertical a 20KN force is applied.

Remember to always check the orientation of the force i.e. whether it acts towards or away from the joint.
For the member at 45 degrees from the vertical.

For the member in the vertical direction (y axis)

Once you have defined all the forces the only thing that remains is to set the parameters we would like to be presented in the results folder.

Click on the results and plots icon and set the parameters you would require to be included in the folder, aspects like the reaction forces.

Let’s combine all the reaction forces (X component, Y component and magnitude) acting on the fixed member.

You can choose to put all the plots in one graph by clicking on the drop down indicating addition to the existing plot.

You can then go ahead and calculate the motion study.

The results of the simulation study are extensively described in the force plot.

The magnitude of the reaction force is 17432N while the X and Y components of the resultant force are 15657N and 7664N respectively.

From this demo we can acknowledge the versatility of the SolidWorks add-ins and general tremendous capability of the software.
