초록

Finite element analysis (FEA) has been used for product optimization involving stability assessment of structures in the design phase before prototype production and deduction of lightening measures to reduce production costs. However, conducting FEA in advance is insufficient to thoroughly examine general structures under various loads. Particularly, construction devices related to human safety undergo a variety of impact loads, which must be considered in the design phase. In most developed countries, impact factors appropriate for different types of structures are derived through long-term experiments, whereas impact factors in Korea are adopted based on results derived in other countries to reduce time and cost. Herein, a method is proposed to calculate the impact factor using an FEA model that has been verified using a simple test. The calculated impact factor can be applied as the static load rather than as a transient response, thus enabling impact stress to be calculated quickly.

Keywords:

Finite element analysis, Rated load, Transient response, Impact load, Impact factor, Dynamic load
