Description

The flow of forces is an auxiliary concept from fluid mechanics for functional analysis and the design of products, in which it is assumed that forces and moments flow through a system like a fluid. There are two applications: The macro force flow for functional, force and moment flow analysis of an entire product and the micro-force flow for the first stress-appropriate design of a component.

Procedure

Principles:

  1. A power flow is always closed.
  2. The type of stress changes in a power flow circuit.
  3. The flow of force looks for the shortest route.


Rules for designing power flow appropriately:

  1. Clearly guide the flow of force.
  2. For rigid, lightweight designs, direct the flow of force over the shortest possible route.
  3. For elastic, work-storing construction methods, the force flow can be guided over a long distance.
  4. Aim for gentle power flow redirection.
