Abstract: To accurately evaluate fatigue life, durability and dynamics of mechanical systems, random vibration simulation tests are required. The success of a simulation test depends heavily on how accurately service loads can be reproduced in a laboratory. Many sophisticated and expensive systems have been developed for these kinds of simulation tests. However, because of high cost and complexity, the usage of these complicated systems is limited. In this paper, an innovative approach to reconstruct service load histories with time series models for random vibration simulation tests will be introduced. With the new approach, service load histories can be accurately regenerated without using sophisticated computer and control systems, and highly accurate random vibration simulation tests can be conducted at low cost and within a short time.

Keywords: service load reconstruction; time series models; modelling; vehicle vibration; simulation; random vibration; fatigue life; durability; dynamics; vehicle design.
