CALCULATION OF VIBRATION COMPOSITION ON MULTIPLE MACHINE ACTION

The calculation of vibration composition under various conditions was researched，such as multiple machine which had same or different frequency of operation on a foundation， one machine which had different rotation speeds components on the principal axis on a foundation，and a reciprocating type machine on a foundation whose rotation motion frequency was double than cylinder reciprocating motion frequency． The suggestions on the calculation method of vibration composition under different conditions were proposed．
