Factors Involved in Designing the Machine Foundation
Q. Explain the factors involved in designing the machine foundation.
The machine foundation should satisfy the following requirements :
- The foundation should be horizontal in level.
- The foundation must be rigid.
- It should be free from vibrations.
- It should transmit both static and dynamic weight of the machine to ground.
- The foundation should be free from defects like cavities, pits, surface cracks etc.
- The foundation should be made from concrete mix i.e. cement, sand water in definite proportion.
- The design of foundation should ensure against sinking of foundation by distributing the load over as much as soil area, in relation with soil bearing capacity.
- The foundation should not slide over the soil due to horizontal thrust of running machine. This is achieved by sufficient frictional resistance between foundation block and soil.
- The foundation should be so designed that the resultant force posses within the block to prevent turning of the machine .
