Calculates the cumulative duration for response values, given the X and Y input data vectors.  The duration will be partitioned into 100 segments.

Syntax

X, Y = Duration(Time, Response)

Arguments

Name

Description

Time

The time vector of real data to analyze (in seconds).

Response

A vector of real data with the same length as Time.

Outputs

Name

Description

X

A vector of the longest times for which the response exceeds the corresponding Y value.

Y

A vector that partitions the Response range into 100 segments.

Example

Given a vector Signal that is sampled at times given in vector Time.

Syntax

X, Y = Duration(Time, Signal)

Results

A plot of Y vs. X will produce the duration function.

Comments

The load duration criterion is a method for assessing the occupant’s injury based on the magnitude and duration of the load.  The data is processed to create a load vs. duration plot.
