5.10 REPRESENTATION BY NODAL METHOD
This method is very simple to get mathematical model of both types of mechanical system.
Let us consider a mechanical system as shown in Fig. 5.24.
Fig. 5.24
The following steps are followed:
| Step 1 | Total number of nodes = Total number of displacements = 3 |
| One reference node is taken in addition i.e., total number of nodes becomes 4. | |
|
Step 2 |
M1 is connected between x1 and reference |
| M2 is connected between x2 and reference | |
| M3 is connects between x3 and reference | |
|
Step 3 |
K1 is connected between x1 and reference |
| K12 is connected between x1 and x2 | |
| K2 is connected between ... |
