GSoC initial contact
Hi, MBDyn teams, I am Runsen Zhang from Beihang University, China. I am a user of MBDyn during my research, and this time, I hope that I can take part in the development of MBDyn, and contribute to it.
Since I have been working on coupling MBDyn with another open-source codes, Chrono::Engine (C::E), I think I can do something about the idea "Improving coupling with another software".
I have finished the first step of entry test, download MBDyn, compile it, and create a test case. I run the example "tm4760" for eigenvalues analysis of a rotator blade.
In the second step, I modified the input file, and create a cantilever beam system (EI=4.2, L=0.25, m_b=0.117675) with added mass at the end (m_a=0.0555) to solve its eigenvalues using MBDyn. Here is the result:
The frequency of the first mode is close to the theory result: f=1/(2*pi)sqrt(3EI/(L^3M_e))=15.62 Hz, (M_e=0.24m_b+m_a) (refer to Friend, R. D., & Kinra, V. K. (2000). Particle impact damping. Journal of Sound and Vibration, 233(1), 93-118.).
Now I am planning on implementing test 3, and improving my draft of the proposal.
