負荷振幅
In nonlinear finite element analysis, the load-time function is a critical feature that defines how loads are applied over time. The software provides the capability to assign varying load intensities at different instances, which is especially useful in simulating real-world conditions where loads are not constant.
To enhance this functionality, the software allows the definition of two amplitude options for the loads. These amplitude options enable users to specify a pattern or a sequence of load values that change over the course of the analysis.
The first amplitude option can define the initial ramp-up of the load, allowing for a gradual increase from zero to the maximum load value, reflecting a more realistic application of force or pressure on the structure. The second amplitude option can describe a subsequent phase, such as a holding pattern, cyclic loading, or a decrease to simulate the removal of the load.
If you only need to deal with a single load amplitude, where all applied loads follow the same function, use ‘Amplitude 1’ as an example. The program will ignore the second amplitude if it is not used.
