Workshop on Vibration Analysis and Experiment for Precision Machines

Date: 05 Nov 2009 - 05 Nov 2009

Venue: Training Room 1, Tower Block, Level 3

Workshop Sponsors

LMS Engineering Innovation and Sunny Instruments Singapore Pte Ltd




Machine vibration is one of the most critical issue for developing precision machinery and equipment as it is the major cause of positioning error during high speed operation. In the past, equivalent static loads were used to design for dynamic loads due to computational complexities of dynamic analysis. With the availability of abundant computer resources and measuring technology, dynamic analysis and diagnosis are more widely used nowadays. It is now possible to predict machine vibration performance before or after the physical machine is built. This workshop will give instructions on how to compute and measure the structural response under dynamic loads and simulated conditions.
