The foundation provides under the superstructure of the vibrating and rotating machine is called the machine foundation. It mainly consists of a block of cement. The basic plan for the machine includes consideration of static loads and engine forces. Whereas, mechanical piles are secondary static loads in the design of mechanical foundations. The moving parts of the machine encourages recreational power, which was a major force in his plans. Active or passive forces are lateral and vibratory in nature, the extent of which depends on the type of machine.
Design Principles
Common standards for base configurations are as follows:
- Firstly, it isolates from adjacent parts of the structure by passing a hole around it to prevent vibration transmission. Moreover, the hatch is filled with a fitting lid or buffer.
- Secondly, the base must be rigid and inflexible to avoid the possibility of tipping it.
- Thirdly, under explicit static, the product of the forces following the machine rules must pass c.g. from the main contact area.
- Fourthly, the weight of the foundation block should be satisfactory. It should have options for absorbing vibration and resisting echoes between the surrounding ground and the machine. Whereas, the weight of the foundation block is generally acceptable to be 2.5 times the weight of the machine.
- Lastly, there is a vibration-absorbing medium between the bottom of the foundation block and the floor where it is present. However, this medium can be a rubber or leather gasket, a layer of sawdust, etc.
Also, springs are sometimes work under the actual machine to prevent vibration from improving. Also as we all know, important information about the machine must be obtained from the manufacturer before any base plan is approved.

Types of Machine Foundation
- Basic block machine
- Box or drawer base
- Wall type
- Framed
- Non-rigid or flexible type
Each type of machine base is represented.
Basic block machine
Foundations of this type include platform landings. Therefore, balanced platforms have enormous mass and minimal natural redundancy.
Drawer-type machine foundation
Palletized machine bases include a large empty block. Whereas, due to the large empty blocks, the mass of this type of foundation is less in contrast to a blocky foundation— also improved natural repeatability.
The wall-mounted machine
The base of a wall-mounted instrument contains multiple sets of walls. However, a piece hangs on the wall that can be closed from the top.
