Commissioning of a Dynamic Test Rig

Commissioning of a Dynamic Test Rig

(OP)
Hey Guys,

I've been tasked with the commissioning/qualification of a new closed loop gearbox test rig.
The previous commissioning I did wasn't very well planned and the tests were almost plucked out of the air making the eventual report writing quite difficult.

This time round I was researching for any standards that determine the testing required for commissioning of a piece of machinery like this.
Could anyone point me in the right direction of an appropriate standard or set of regulations to determine the testing needed?

My other idea was to look at the regulations around CE marking to see if that could possibly help?

Thanks
Steve

RE: Commissioning of a Dynamic Test Rig

It seems unlikely that you will find any standards that address this apparently custom designed equipment.

Commissioning tests are done to confirm that the equipment achieves its design requirements.

So start with the design requirements. Develop tests that confirm the equipment can do what it was designed to do.

RE: Commissioning of a Dynamic Test Rig

What industry will use this gearbox? See if they have standards. For automotive, the SAE has standards for almost everything. However, if there are established testing standards, the time to read them is BEFORE you build the test rig.

Thanks MintJulep, I will get hold of the design spec and try to build the tests around that.

dgallup, the gearboxes will be used by our customer eventually but the test rig itself is a piece of in-house kit. It was designed by a "test rig design" company, so its quite likely they have followed available standards.
I tried checking SAE for "commissioning", "Test rig", "Qualification" but I didnt have much luck.

This is about the best I've found so far:

RE: Commissioning of a Dynamic Test Rig

You are not going to find specifications for test rigs, you need to look for specifications for the objects you are going to test. That is how you know what the test rig needs to do. I would not arbitrarily assume that a "test rig design company" would necessarily follow any standard. We always write a machine spec for test equipment we buy.

I just input "transmission" in the SAE spec database and found:
SAE J 651 Title: Passenger Car and Light Truck Automatic Transmission and Automatic Transaxle Test Code
SAE J 652 Title: Truck Transmissions—Test Code
SAE J 2453 Title: Manual Transmission and Transaxle Efficiency and Parasitic Loss Measurement
SAE J 1540 Title: Manual Transmission Efficiency and Parasitic Loss Measurement
SAE J 1618 Title: Continuously Variable Transmission Test Code for Passenger cars
SAE J 2525 Title: SAE Design Guideline: Metal Belt Drive Continuously Variable Ratio (CVT) Automatic Transmissions

If you are going to CE mark it, writing test procedures will be part of that process. If it is a bespoke machine then you will need a bespoke acceptance test procedure.
