Experiments of SMA actuators for mechanical oscillators

Morito Katsuyama

As an alternative actuator for mechanical oscillator, I found SMA wire actuators. SMA wire actuator is a linear actuator that has the similar function to the SCP actuators. I decided to test the practicability of SMA actuator as an actuator of the mechanical oscillator because there are some advanta...

Fabrication of mechanical oscillator with PET sheet

Morito Katsuyama

This past week, I have finished writing the draft of the report of the fabrication of a mechanical oscillator with a monostable beam. Then, I started to work on the new project which aims to produce an integrated robot with the system of a mechanical oscillator with Wenzhohng. To begin with, I learn...

Fabrication and testing of monostable beams

Morito Katsuyama

After fabricating the first prototype of a monostable beam, I fabricated a bunch of prototypes of monostable beams with different mechanical properties this week. After the fabrication, I tested the monostability of these prototypes of a monostable beam. As a result of experiments, monostability was...

Prototyping of Monostable beams

Morito Katsuyama

This week, I finally prototyped a monostable beam and its testing frame. The monostable beam was cut out from PTFE plats by a laser cutter. The cutting by a laser cutter was pretty precise and the shape of the monostable beam was almost the same as its original design. After the cutting process of t...

Pre-Lab and preparation for experiments

Morito Katsuyama

Before starting experiments of prototyping of mechanical oscillator, I wrote a Pre-Lab in order to clarify the purpose and method of experiments and perform experiments efficiently. I also figured out the plan of experiments in this quarter with this Pre-Lab. From now on, based off this Pre-Lab, I...

Property simulation of a monostable beam and a CSCP actuator

Morito Katsuyama

Last week, I simulated mechanical behaviors of monostable beam and CSCP actuator respectively to design a prototype of mechanical oscillator. This figure shows switching force of monostable beam as a funtion of initial rise and thickness of monostable beam. From this figure, we can find how much for...
