Shock Response
Browser-based tools for first-pass results for rigid body response to being dropped or impulse loaded.
Tip:
Documentation PDFs include user information, solution methods, assumptions and references.
Drop Shock
1D Drop Shock
Shock response to a rigid body dropped from a height onto a spring and damper.
User input weight and drop height.
User input spring and damper properties.
Outputs include the weight acceleration versus time. The result is animated.
Impulse Loaded
1D Shock Response
The body response to an impulse load is estimated. Impulse options include triangular, step and sawtooth. Random input is also available with a user input PSD profile.
User input weight.
User input spring and damper properties.
If a random input is selected the user defines a PSD profile.
Outputs include the body accelerations versus time. The motion is animated.
Drop Shock
3D Dropped Weight Response
Similar to the 1D drop module but simulates a 3D box defined by the user.
User input box size and weight.
User input corner spring and damper properties.
User input drop height and angle orientation to the ground.
Outputs include box corner responses and box CG response versus time. The drop and response are animated.
Quick selection
Which module should I use?
1D drop shock : 1D response to the suspended box being dropped from a height.
Impulse loaded 1D box : response to impulse loads including random.
3D Box drop: 3D response to the box being dropped at a height and angle to the ground

Methods, limitations, and responsibility Read once
These modules implement physics-based, low-order models for rapid engineering insight. They prioritize speed and transparency over high-fidelity dynamics simulations Assumptions, boundary conditions, and correlations used are documented in the PDFs and within the modules. Users are responsible for verifying applicability and results for their specific use case.
