Abstract

The invention discloses a high-temperature creep test device applied to an exhaust system, the high-temperature creep test device applied to the exhaust system comprises a base platform, a temperature control box, a computer and at least two groups of testing mechanisms, and the temperature control box, the computer and the at least two groups of testing mechanisms are fixedly connected to the top surface of the base platform; the testing mechanism comprises a bearing bracket, a tubular furnace, a plurality of weights, at least two groups of guide columns, a weight tray, a distance measuring sensor, a first fixing rod, a second fixing rod, a first chuck, a second chuck and a test sample which are connected with one another; the test sample piece is positioned in the accommodating space of the tubular furnace, and the tubular furnace is fixedly connected with the bearing bracket; the distance measuring sensor is located below the weight tray and fixedly connected with the bearing support. The test device provided by the invention realizes real-time acquisition of time, temperature and creep curves, realizes accurate temperature control of the temperature in the furnace, and can realize parallel connection and simultaneous control of a plurality of tubular furnaces, thereby improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of automobile exhaust systems, and in particular relates to a high-temperature creep test device applied to exhaust systems. Background technique [0002] At present, when the hot-end metal of the automobile exhaust system is working, the temperature can reach more than 900°C. The material is subjected to continuous load under high temperature, and it is prone to problems such as creep failure. With the increase of the exhaust temperature of the national six exhaust products, The service temperature of the silicone lug has also risen, and its high-temperature creep performance is also an indicator that needs to be evaluated under long-term load. [0003] The high-temperature creep testing equipment in the related art is used to test the mechanical properties of materials. In addition to conventional creep and endurance tests, it can also perform stress relaxation tests, high-temperature short-term tensile te...
