Graphs for Quasi-Static Analysis

Yunchen (Blaire) Yu

The graphs seem to suggest that the smaller the initial rise of the bistable beam, the longer the SCP actuator, and the more influence temperature change has on the force generated by the actuator, the easier for the bistable beam to snap through. The trends align with our expectations even though t...

Quasi-Static Analysis of the Bistable Beam

Yunchen (Blaire) Yu

Below are the graphs describing the relationships between time and the displacement of the midpoint of the bistable beam, assuming a quasi-static state of the beam. More explanations are needed, and we need to vary some of the parameters to see how they affect the shape of the graph.

Static Response of Pre-Compressed Beams

Yunchen (Blaire) Yu

These two graphs are based on my Matlab simulations of the behavior of a pre-compressed bistable beam under a point force. The segmented one is the actual data due to some errors, but the adjusted version of the graph (ideally elinimating some errors in calculation) matches the results in previous r...

Reduced-Order Model

Yunchen (Blaire) Yu

For the last two weeks, I tried out tackling the differential equation that describes the motion of the bistable beam using a reduced-order model of w(x,t), the transverse deflection of the beam. By approximating w as the combination of some functions of only x or only t, I was able to replicate the...
