Different Modes of Combination in Response Spectrum by SolidWorks Simulation

The response spectrum method is used to compute inertial response, estimates of response quantities developed for each mode, each direction of excitation and each input, if multiple inputs are considered. The total response is then formed by summing over all modal component, spatial component and excitation component responses. It estimate the structural response to short, nondeterministic, transient dynamic events. Examples of such events are earthquakes and shocks. Since the exact time history of the load is not known, it is difficult to perform a time-dependent analysis.

It is a widely used procedure for performing elastic dynamic seismic analysis, represents the set of the maximum acceleration, velocity or displacement responses of a family of single-degree-of-freedom (SDOF) damped oscillators. 

Fig: 1

For a given time period of system, maximum response is picked. This process is continued for all range of possible time periods of SDOF system. Final plot with system time period on x-axis and response quantity on y-axis is the required response spectra pertaining to specified damping ratio and input ground motion as acceleration, velocity or displacement response.

Factor Influencing Response Spectra:

1. Damping in the system

2. Time period of the system

3. Energy release mechanism

Errors in Evaluation of Response Spectrum:

Truncation Error: - In general, a truncation error exists in numerical methods for
integrating differential equations.

Rounding the Time Record: - For earthquake records digitized at irregular time intervals, the integration technique proposed in this report requires rounding of the time record and the attendant error depends on the way the rounding is done. For round-off to 0.005 sec, the average error in spectrum values is expected.

Error Due to Discretization: - In any numerical method of computing the spectra, the
response is obtained at a set of discrete points. Since spectral values represent
maximum values of response parameters which may not occur at these discrete points,
discretization introduces an error which gives spectrum values lower than the true
values.

Multi degree of freedom (MDOF) systems are usually analyzed using Modal Analysis. A
typical MDOF system with ‘n’ degree of freedom. The system when subjected to ground motion undergoes deformations in number of possible ways. These deformed shapes are known as modes of vibration or mode shapes.


In SolidWorks Simulation, we can predict the Displacement, Maximum Stress Induced and frequency with respective mode shapes of the system. with response as acceleration, velocity or displacement input to the system, with irrespective of the system type, the system can be 

Regular or Irregular as shown in Fig:2 & Fig:3.

  Fig:2(irregular Structure)


Fig:3(Regular) 

Regular Structure:

The design shall be approximately symmetrical in plan with respect to two orthogonal axis with flowing assumptions:

1. Location of joints with equal spacing in the design.

2. No horizontal or vertical irregularity of the structure

3. No change in material or shape of the structure cross section.

Irregular Structure:

If the design does not follow any assumptions of the regular system, becomes irregular structure. Most of the mechanical designs are Irregular in nature, as there may be material changes to the main members to improve the strength of the design.

There are different methods that are used for combining the response of each direction of system the methods for MDOF system are as follows:

1. Square root of sum of squares (SRSS) Method

2. Absolute Sum (ABSSUM) Method

3. Complete quadratic combination (CQC) Method

4. Naval Research Laboratory (NRL)

Square root of sum of squares (SRSS) Method:

The maximum response is obtained by square root of sum of square of response in each mode of vibration, the effect is calculated for each individual Frequency of the system with the defined response at different directions, these responses are summed up and an averaged.

Limitation of SRSS:

· There is a poor estimator of peak responses when applied to systems with closely spaced natural periods.

· Significant errors are caused when working with Irregular system.

Absolute Sum Method:

The peak responses of all the modes are added algebraically, assuming that all modal peaks occur at same time. The maximum response is given by:

Complete quadratic combination (CQC) Method:

The previously illustrated errors which are inherent in absolute sum or the SRSS method are rectified with CQC, The maximum response from all the modes is calculated as:



rmax is the maximum response

ri, rj are maximum responses in the ith and jth modes

αij is Cross Modal Coefficient

ξ is Modal  Damping Ratio, β is Frequency Ratio [ ]

Naval Research Laboratory (NRL) Method:


The Naval Research Laboratory (NRL) method to combine the peak responses from all mode shapes into overall displacements and stresses. It is modification of the SRSS Method, takes the absolute value of the response for the mode that exhibits the largest response and adds it to the SRSS response of the remaining modes the maximum response from all the modes is calculated as:

Where {uj}max represents the mode with the largest response among all modal responses.


All the above methods discussed are available in SolidWorks Simulation, according to the structure type and the user requirement, we can define the mode combination method as shown in the Fig: 4.

Fig: 4

We had discussed the different mode combination techniques in Response Spectrum, and the purpose of the different techniques and also the model equations of the techniques with their limitations.

Top Enhancements in SOLIDWORKS Simulation 2022

In the field of design and production, which are the major fields for the new product development in industry, as technology is advancing the process we do should be changing according to the new enhancements, so that we can works faster & smarter.

The major important task in NPD is the product reliability & Performance in the real time conditions, to predict these at the design stage we can do an virtual validation with SOLIDWORKS Simulation, as mentioned previously with advanced technology development in the field of FEA, and implementing them in SOLIDWORKS Simulation. There are few enhancements in the SolidWorks 2022 in Simulation(FEA) they are listed below with detail:

1. Linkage Rod Connector

2. Blended Curvature Based Mesh

3. Parallel Processing

Linkage Rod Connector

   


In an 4 bar linkage mechanism we use an Intermediate link that connects both the links as shown in the Fig: 1, the main purpose of the Intermediate link is to transfer the force exerted on the one link to the other link. This Intermediate link can be defined as an boundary condition so that the mesh size can be reduced  and speed-up the simulation. In SolidWorks Simulation 2022 an new feature called Linkage Rod Connector can be used in the place of the Intermediate link. We can define different types of joint connection between the joints i.e.

a. Rigid Joint:

A rigid joint prevents any rotations or deformations. A linkage rod connector with rigid joints can transfer all moments from one part to another.

b. Pivot Joint:

A pivot joint allows only one rotation about the axis normal to the connector's axis.

c. Spherical Joint:

A spherical joint acts like a ball and socket joint where the ball can rotate inside the socket, but it cannot dislocate from the socket.We can list a linkage rod connector's forces such as shear force, axial force, bending moments, and torque after you run a simulation.

 

Blended Curvature Based Mesh

Meshing is the important task when we are working in the field of FEM or CFD. It is always good to have an automated mesh algorithm to mesh the complex models, so that we can eliminate the errors that are created when meshing. As we know SolidWorks simulation uses automated mesh algorithm, for refinement there is an new enhancement in the SolidWorks 2022 i.e. Blended Curvature Based Mesh, as shown in Fig:2, in this the course mesh can be defined to bodies that are not critical for analysis & can applying the Mesh control to the selected components that are critical, so that the analysis time can be reduced. After creating the mesh, with Mesh summery we can know the element size that is assigned to the individual components.

 Fig:2


 

Blended Curvature-based mesh in 2022

Parallel Processing:

 The major task in the field of FEA is, solving the meshed elements with their respective boundary condition PDE’s, with the technology enhancement we are able to make this process by function-based stiffness data communication replacing file-based processing, which take advantage of extending parallel processing speed-up with the iterative solver to all connectors and most features, the comparison of 2020 & 2021 is shown in the Fig:3
