Design of dynamically loaded foundations for pumps

2019-5-13  work was to study the design process of dynamically loaded foundations. The process of calculating foundations for vibrating machines is long and complex, it includes many factors that should be taken into account. That is why the task was to create a manual and the Excel file for fast calculation.

Design Considerations for Dynamically Loaded Equipment ...

The design of foundations to support large items of mechanical equipment is becoming increasingly important. In many industrial environments the consequences of vibration are severe. For example, sensitive processes can be rendered inoperable, process and mechanical equipment can be damaged, and work conditions can become intolerable.
