Design for Assembly Using FEM

Product design for assembly usually follows the concept of minimizing the number of parts. This approach can result with fewer assembly operations and consequently with lower assembly costs. But, from the market and sale point of view the requirements sometimes demand different philosophy in product design. The packaging and transportation criteria can be expressed with the sentence "smaller is better". It means that large products should be designed applying the disassembling (modular) construction, the product has to be divided into smaller sections (more parts) joined by appropriate assembling techniques. Where are the acceptable dividing planes and what are the assembling techniques which would provide product functionality, quality and stiffness? These are the issues the paper deals with using the finite element method. This paper describes the designing of the handcart FE models for the simulation of assembling techniques, with the aim to find out the most appropriate solutions without the use of the conventional workshop prototyping. It addresses the problems of simulating the assembly FE models, bolt fits as well as friction and contact conditions.
