Dampers can be assessed in two ways: - in given assembly conditions and at a given stress (mounted in a sleeve), - in real operating conditions (mounted in a tube yoke). 2 TEST CONDITIONS: RUBBER PART MOUNTED IN A SLEEVE 2.1 Description of the test components Determine the shape of the sleeve: see drawing at appendix 1. Measure the dimensions of the rubber part to determine the stress. Fit the rubber part into the sleeve. 2.2 Fitting the rubber part into the sleeve - Insertion length: see overall drawing for the use of the rubber part. - Insertion conditions : - oil, - ambient temperature - speed: 10 mm/min - guide sleeve and contact area (see sketch below) Rubber part without bounding Rubber part with internal support and bounding
