TODO List¶

Scope¶

This document outlines the proposed improvements to the tdof_mck_forced_Response.py example. These improvements aim to enhance the handling of harmonic motion and the response to multiple excitations in a two-degree-of-freedom (TDOF) mechanical system.

Improvement 1: Using HarmonicMotion Class¶

TODO: Replace convert_harmonic_to_cos and convert_harmonic_to_sin functions with the HarmonicMotion class for more efficient and accurate harmonic motion handling.

# Current Implementation
from np_vmd.misc import convert_harmonic_to_cos, convert_harmonic_to_sin

# Proposed Implementation
from np_vmd.misc import HarmonicMotion
# Code demonstrating the use of HarmonicMotion class

Improvement 2: Handling Multiple Excitations¶

TODO: Address the issue of a system having more than one excitation. The response should be a superposition of responses for each excitation separately.

Proposed Solution:

Create a TotalResponse class that handles the response of the system to a single excitation.
Create a MultiExcitationResponse class that manages multiple excitations by delegating the work to the TotalResponse class for each excitation.

# Example of the TotalResponse class
class TotalResponse:
    def __init__(self, ...):
        # Initialization code

# Example of the MultiExcitationResponse class
class MultiExcitationResponse:
    def __init__(self, ...):
        # Initialization code

Conclusion¶

Implementing these improvements will enhance the capabilities of the TDOF system analysis by providing more robust handling of harmonic motion and accommodating multiple excitations effectively.

Further Work¶

Implement and test the HarmonicMotion class in the context of the TDOF system.
Develop and validate the TotalResponse and MultiExcitationResponse classes.
