Sentence examples for design of machine foundations from inspiring English sources
The isolation of vibrations from the surroundings is one of the important problems in the design of machine foundations.
In consideration of the dynamic load additionally generated, the design of the machine foundation is performed in the course of the following two steps.
These are assumptions that would be generally valid for properly designed machine foundations where very small strains should be expected.
It was thought that the design concepts of the machine foundation, assuming that the additional dynamic load due to machine vibration equals to 50% of the static load in current code, is excessively conservative.
The word was "cybernetics" -- the design of machines to make better machines than those produced by human hands.
In addition, in IS 2974 [4] which is the design criteria of the Reciprocating Motion machine foundation of Indian Standard Institution, it is defined that the ground stress below the foundation cannot exceed 80% of the allowable stresses under the static loading.
Firstly, calculate the natural frequency and displacement of the machine foundation system subjected to the vibration load by dynamic load to avoid resonance, and design to satisfy the allowable displacement given from the machine manufacturer.
Next, the strength, stability and ground bearing capacity of the Machine foundation based on static load are evaluated, and in this case, the pseudo-static design considering the additional dynamic load is made up.
In other words, in the numerical model, when the maximum allowable displacement of the machine foundation is consistently applied to the foundation, it showed that the stress of about 160 kPa might be additionally generated to the pile head.
Load carrying capacity is often the governing factor in the design of pile foundations.
