Analyse Angular Momentum for a Model — analyse_angular_momentum

This function computes the segmental angular momentum about the centre of mass of a body model based on position and velocity kinematics over time, returning the results or saving them to a file.

Usage

analyse_angular_momentum_com(
  model_file = "Model_SCALED.osim",
  body_pos_df = pos_df,
  body_vel_df = vel_df,
  file_output = "angular_momentum.sto",
  in_degrees = TRUE,
  write_file = TRUE,
  return_object = FALSE
)

Arguments

model_file: A string specifying the model file (in .osim format).
body_pos_df: A data.frame containing the body position data (usually read from .sto format).
body_vel_df: A data.frame containing the body velocity data (usually read from .sto format).
file_output: A string specifying the output file for the angular momentum results.
in_degrees: Logical; if TRUE, input angles and velocities are assumed to be in degrees. Defaults to TRUE.
write_file: Logical; if TRUE, the function writes results to a file. Defaults to TRUE.
return_object: Logical; if TRUE, the function returns the computed angular momentum as a data frame.

Value

If return_object = TRUE, a data frame containing the angular momentum values for each body at each time step.
