1. Apparatus for the vibration testing of a catalytic converter comprising:
- a support structure for rigidly supporting a catalytic converter to be tested;
a vibrator connected to the support structure for vibrating the support structure and the catalytic converter under predetermined vibration conditions;
a heater for preferentially heating a catalyst support honeycomb mounted within the converter; and
a sensor for attachment to the honeycomb, the sensor being adapted to sense force or acceleration applied to the honeycomb in the course of testing.

Abstract
A method and apparatus for testing the durability of a catalytic converter incorporating a catalyst support honeycomb supported by a resilient mounting material within an exterior converter enclosure, the method comprising vibrating the exterior of the converter enclosure while the converter is heated to a predetermined testing temperature and while the force or acceleration applied to the catalyst support honeycomb by the vibrating exterior enclosure and resilient mounting layer is measured.

12. A method for testing the durability of a catalytic converter incorporating a catalyst support honeycomb supported by a resilient mounting material within an exterior converter enclosure which comprises the steps of simultaneously:
-
vibrating the exterior converter enclosure;
whileheating the catalyst support honeycomb to at least one predetermined testing temperature; and
whiledetecting at least one of an force or an acceleration applied to the catalyst support honeycomb by the vibrating exterior enclosure and resilient mounting material. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
