How to choose a suitable shock absorber

Model selection

Rotating motion・Vertically rotating fall, descend・Free fall


Mass of colliding object M ： kg
Distance to the gravity center of colliding object Rg ： m
Distance to the Absorber R ： m
Initial central gravity angle of collision object α ： degree
Colliding angle of collision object β ： degree
Numbers of soft absorber N ： pieces

* If inputting other figure rather than "1", only FIXED TYPE shall be selected.

Number of collision per minute C ： times/minutes
Moment of inertia I ： kg・m²
　

Calculating Moment of inertia

Choose the shape
