Adams/Insight User Responses

Besides the standard library of responses based on Adams/Chassis reports, Adams/Insight provides some general utilities to create custom responses for processing Adams request data.

User Response Naming Convention

A strict naming convention is required for user responses added to Adams/Insight experiments with Adams/Chassis.

Each event included in the experiment has a prefix, which appears in the response hierarchy in Adams/Insight:

When adding user responses, you must begin the name of your response with the prefix corresponding to the event with which the response is associated.

Example: Following the naming pattern from the example above, the following user response names are valid:

Valid user responses names:

•	e_001_achassis_gs_full_sys_swep_1_max_latacc

•	e_002_achassis_gs_full_sys_ride_2_average_left_toe

•	e_003_achassis_gs_full_sys_comp_3_left_toe_at_6_seconds

Invalid user response names:

•	max_latacc

•	average_left_toe

•	left_toe_at_6_seconds

Single Request User Responses

Similar to Adams/Chassis 12.0, you can specify single user responses in Adams/Chassis 2005. In Adams/Chassis 2005, there are supplemental method types available to process a vector of data.The following table shows the types available in Adams/Chassis 12.0 and 2005:

 

12.0	2005
min	min
max	max
absmin	absmin
absmax	absmax
initial_value	initial_value
final_value	final_value
range	lstrange *(Name change)
average	average (or mean)
	New types
	rms
	sqsum
	stdev
	sum
	sumsq
	var (variance)
	skew (skewness)
	kurt (kurtosis)

 To create an  Adams/Insight response for one of these, create a new response, select Scalar Response Type, and enter a string with the following syntax in the Variable text box:

            plts:<type>:req_<id>:<col_number>[:time_range:<tmin>:<tmax>]

Required arguments

type - One of the types listed above (max, min, and so on)
id - Numerical Adams request ID
col_number - Adams request column number (1 - 6)

Optional Time Range feature (must specify minimum and maximum time)

min - Minimum time for output

tmax - Maximum time for output

Examples

Maximum left front toe:

    plts:max:req_1080:1

Minimum lateral acceleration:

    plts:min:req_1041:1

Final steering wheel angle:

    plts:final_value:req_1090:1

Maximum left front toe between 1 and 3 seconds:

    plts:max:req_1080:1:time_range:1:3

Request Value at Specific Time 

This user response processes the value of a request at a specific time. To create an Adams/Insight response for this type, create a new response, select User Response Type, and enter a string with the following syntax in the Variable text box:

            time_value:<time>:req_<id>:<col_number>

Required arguments

time - Simulation time to process request (must correspond to an output step)
id - Numerical Adams request ID
col_number - Adams request column number (1 - 6)

Examples

Left front toe at 2 seconds 

    time_value:2:req_1080:1 

Lateral acceleration at 4 seconds 

    time_value:4:req_1041:1
   

Polynomial User Responses

The second kind of user response is polynomial. This type of response creates a series of responses corresponding to the coefficients of a polynomial. The polynomial is the best fit curve when plotting one Adams request versus another.  The number of responses corresponds to (order+1), where order is the specified polynomial curve order.

To create an AdamsAdams/Insight polynomial response, create a new response, select User Response Type, enter a string with the following syntax in the Variable text box, and enter (order+1) into the Columns text box:

            poly:<order>:req_<id1>:<col_number1>:req_<id2>:<col_number2>[:time_range:<tmin>:<tmax>]

Required arguments

order - Order of polynomial response
id1 - Adams request ID for polynomial independent values
col_number1 - Adams request column number (1 - 6) for polynomial independent values
id2 - Adams request ID for polynomial dependent values
col_number2 - Adams request column number (1 - 6) for polynomial dependent values

Optional Time Range feature (must specify minimum and maximum time)

tmin - Minimum time for output

tmax - Maximum time for output dependent values

Examples

Polynomial response, quadratic, steering wheel angle as a function of lateral acceleration:

    poly:2:req_1041:1:req_1090:1

Polynomial response, cubic, left front toe as a function of left spindle rise:

    poly:3:req_5109:3:req_1080:1

Polynomial response, cubic, left front toe as a function of left spindle rise between 3 and 4 seconds of simulation time:

    poly:3:req_5109:3:req_1080:1:time_range:3:4
