1. Objective and test subject

– Test objective

Determination of machine vibration by measurements on non-rotating parts.

– Test subject

• Reciprocating machines (marine propulsion/auxiliary engines, diesel engines, generator set engines, reciprocating pumps, and diesel locomotive engines) with power ratings above 100kW (similar to test 44).
• The test applies to both types of machines: mounted on rigid supports and mounted on resilient supports.

2. Experimental procedure

Steps to perform:

• Equip fully with devices, transducers, and test samples.
• Perform sample measurement.
• Process and report results.

1,1	< 17,8	< 1,12	< 1,76
1,8	< 28,3	< 1,78	< 2,79
2,8	< 44,8	< 2,82	< 4,42
4,5	< 71,0	< 4,46	< 7,01
7,1	< 113	< 7,07	< 11,1
11	< 178	< 11,2	< 17,6
18	< 283	< 17,8	< 27,9
28	< 448	< 28,2	< 44,2
45	< 710	< 44,6	< 70,1
71	< 1 125	< 70,7	< 111
112	< 1 784	< 112	< 176
180	> 1 784	> 112	> 176
NOTE The values were derived from constant displacement in the range 2Hz to 10Hz, constant velocity from 10Hz to 250Hz and constant acceleration from 250Hz to 1.000Hz.

Role – importance of the test method for the determination of mechanical vibration of reciprocating machines with power ratings above 100kW by measurements on non-rotating parts

The test method for the determination of mechanical vibration of reciprocating machines with power ratings above 100kW by measurements on the non-rotating parts conducted by the DASM Institute helps provide useful information, meeting the practical needs of customers and enterprises wishing to:

• Control vibration, isolate vibration sources, prevent vibration, and implement mitigation measures to avoid health and safety risks without negatively impacting the surroundings.
• Material, component, and equipment manufacturers; consulting units – design units wanting to achieve effective damping and vibration isolation..., and wanting to evaluate the effectiveness of vibration treatment and mitigation measures...
• Help control quality during production, optimize research and development of products and materials aiding in damping and vibration isolation related to reciprocating machine vibrations with power ratings above 100kW.
• Commercial/consulting businesses have a verified basis to propose and implement solutions prioritizing suitable machinery, equipment, and technical-technological initiatives capable of minimizing vibration impacts.
• Control equipment condition, early detect signs and causes of damage to proactively maintain machinery.
• Support legal dispute resolution, litigation, forensic examination requests, measurement, and sample analysis in cases of vibration violations exceeding technical standards.

At the same time, DASM will conduct consulting and design work to create shape/structure/material solutions to adjust the anti-vibration and damping functions of the test sample in a streamlined, efficient, and cost-effective manner (in case standards are not yet met).

If previously you had some concerns and worries and had to spend many fees for similar activities abroad, now you only need to contact DASM. The entire remaining process will be proactively implemented by us as a complete package in the shortest time to complete the customer experience about us: DASM provides acoustic consulting services with truly superior quality, the most competitive prices in the industry along with thoughtful and dedicated customer care policies.
