Impact response of preloaded structures with revolute joints

PDF Version Also Available for Download.

Description

Many structural components designed to support static loads must also demonstrate the ability to withstand low probability events that can produce impact loading. For some constructs the structure is not only subjected to the initial impact, but is also subjected to rebound impacts as well. In some designs, support structures must be moved in and out of position as part of normal operations. These structures often employ revolute joints to allow the motions. In addition, functional requirements may require that a significant preload exist within the structure during normal operating conditions. This paper present the methodology needed for simulating the ... continued below

Description

Many structural components designed to support static loads must also demonstrate the ability to withstand low probability events that can produce impact loading. For some constructs the structure is not only subjected to the initial impact, but is also subjected to rebound impacts as well. In some designs, support structures must be moved in and out of position as part of normal operations. These structures often employ revolute joints to allow the motions. In addition, functional requirements may require that a significant preload exist within the structure during normal operating conditions. This paper present the methodology needed for simulating the impact response of preloaded structures with revolute joints. A three-dimensional revolute joint is presented for use in explicit time integration analysis of problems with severe impacts. The computational engine used for the transient solution of preloaded structures is discussed. These developments are used in the analysis of a preloaded platen subjected to drop loads. The resulting transient response of the system is presented.
