Weight reduction

•Example: Optimized shapes of wall thickness of a crankcase

Target of the project

Weight reduction because of

  • CO2  reduction

  • car weighttargetgoals

  • cost reduction

Result of the project

  • Weight reduction 25%(original weight 12.5 kg)

  • Amortization of all costs within 1 year

  • Saving potentials per year 2 Mio €

•

 

Example: Maximum material removement 

•

•
Standard design
•hofer weight-optimised solution
 
 
  • Weight reduction up to 15%
  • Cost reduction 15%

 

•Example: Optimization of gearbox housing

FEM calculation for:

  • Realization of a homogeneous stress distribution
  • Durability estimations
  • Evaluation of acoustical behavior

  

 
Problem analysis
hofer solution
 
Failure because of
inhomogeneous stress
distribution
Problem analysis through
simulation of the failure
•Systematic solution approach
through FEM and expert analysis

 

•Example: Aluminum versus Magnesium optimized housing

•Aluminium design
•Magnesium design
   

  • •Equal stiffness and strength
  • 35% less weight
  • Equal manufacturing costs

 

 

•Example: Rib optimization

 

Problem analysis hofer solution
 

 

 

•Reference project (gearbox housing):

Target:

  • achieve same strength and stiffness

  • achieve same acoustic behaviour

  • use identical machines and assembly line

  • weight reduction

 
Solution:
  • - Component with 18 % less weight, 18 % less costs, same geometrical properties

 
Method:
  • FEM Simulation

  • complete redesign

  • casting simulation
