Problems solved by technology

The simulation calculation is convenient, fast, and low in cost. There are many simulation calculations for connecting rods, but they can only analyze and verify the trend of fatigue reliability, and the boundary conditions are uncertain; the actual machine test can reflect the real working conditions of the connecting rod. However, the test period is long, the cost is high, and the strengthening test cannot be carried out; the simulated fatigue test can be carried out with a shorter cycle and higher efficiency, and the fatigue test can be strengthened to test the fatigue characteristics of the connecting rod more comprehensively
[0003]At present, there is no self-developed connecting rod tension and compression simulation fatigue test bench in China

Description

technical field [0001] The invention relates to an engine test bench, in particular to a connecting rod tension and compression simulation fatigue test bench. Background technique [0002] The connecting rod is the core component of the reciprocating piston internal combustion engine, and it is also one of the main components of the internal combustion engine that bears a large alternating load. Its reliability directly affects the safety of the internal combustion engine. At present, the main means of research on the fatigue reliability of connecting rods include simulation calculation, actual machine test and simulated fatigue test. The simulation calculation is convenient, fast, and low in cost. There are many simulation calculations for connecting rods, but they can only analyze and verify the trend of fatigue reliability, and the boundary conditions are uncertain; the actual machine test can reflect the real working conditions of the connecting rod. However, the test c...
