The invention relates to a testing device of a pad for an automobile tail gas catalyst. A push rod is vertically arranged on a base, a first force sensor is arranged between the push rod and the base,a lower heating clamping block is arranged at the end of the push rod, an upper heating clamping block is arranged above the lower heating clamping block, and a first servo motor is connected with the upper heating clamping block and can control the same to move up and down relative to the lower heating clamping block; a temperature control system comprises heating devices arranged on the upper heating clamping block and the lower heating clamping block, an air-cooling device and a temperature sensor. The testing device is simple in structure, compact in design, convenient to use and capableof accurately controlling temperature of a pad test piece and encapsulating gap thickness to simulate performance of the pad under different working conditions and can be used for testing multiple performances like surface pressure, aging endurance and friction coefficient of the pad, testing time is saved, and testing cost is lowered.
Description
technical field [0001] The invention relates to a test device for a gasket of an automobile exhaust catalyst, belonging to the technical field of detection devices. Background technique [0002] With the decline of automobile prices and the improvement of the consumption environment, my country's automobile market has maintained an average annual growth rate of more than 10%. However, while automobiles bring convenience to society, they also bring a serious problem - automobile exhaust pollution . Solving the harm of automobile emissions to environmental pollution has become one of the important topics studied by major automobile manufacturers in the world for many years. One of the important measures - pollution control device, through the honeycomb ceramic substrate containing Pb and other precious metal coatings, the harmful gas in the exhaust gas is converted into harmless CO 2 , N 2 and H 2 O, so that vehicle exhaust emissions can be effectively controlled. [0003]...
