Season's Greetings

As the year draws to a close we would like to express to all our customers and friends
our gratitude for sharing business with us and for your past commitment to our company.

In Christmas times one can hear a lot of ringings.
So, we wanted to make our own ringing bell with much fun and virtually, of course, and with sound.

In an effort to reach out and help others to also have festive feelings we provide
a charity to UNICEF this year again.

The film is showing the ringing of a bell, which is hit by a clapper.
It is best replayed with sound.
The deformation of the bell is shown in colours on the bell's surface.
A FE analysis was performed by modal dynamics in time domain with the hit of the clapper as excitation.
The motion of the bell was suitably superimposed using the rigid body mode of the bell.

The geometry of the bell was taken from the following source:

The sound has been created from the calculated time signal using the software
