Base Shake
Browser-based tools for first-pass results for rigid body response to being base loaded.
Tip: Documentation PDFs include user information, solutions methods, assumptions and references.
Base Shake
3D Base Impulse Loaded
3D rigid body response to a rigid body on a springs and dampers at each corner to being base impulse loaded.
User defined weight and 3D box dimensions.
User defined spring and damper properties at each corner
User selected impulse load and time duration. Load options include ½ sine, triangular, sawtooth and rectangular.
Outputs include dynamic response with acceleration of the body CG and each corner versus time. The motion is animated.
Base Shake
3D Body Response to a Random Vibration Base Input
3D rigid body response to a rigid body on a springs and dampers at each corner to being base impulse loaded by a random vibration input defined by a user input PSD profile.
User defined box dimensions and weight.
User defined spring and damper properties at each corner.
User defined PSD from which a random vibration input will be determined.
Outputs include dynamic response with acceleration of the body CG and each corner versus time. The motion is animated.
Validate results independently with further detailed analyses and testing.
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 rigid body 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.
