Technical Field
[0001] The invention relates to the technical field of equipment life testing, and in particular to a life simulation testing system and a testing method for a resin pipe of a forklift gantry. Background Art

It is mainly used to detect the ultimate life of products in the manufacturing industry, so as to further optimize the performance of the product; The test equipment used for simulating the life of resin tubes of forklift masts is a resin tube connected to the forklift mast. By setting parameters such as the pressure, pulse frequency and operating temperature of the forklift mast, and simulating the motion trajectory of the rollers on the forklift mast, the effective number of reciprocating motions of the resin tube under this specific operating condition, that is, the life of the resin tube, is verified. Through these data, the parameters of the resin tube can be adjusted, the resin formula can be modified, the buckling parameters can be modified and adjusted, etc., so as to further optimize the resin tube. However, for the current resin tube simulation test device, the temperature will rise during the frequent pulling of the resin tube. The final temperature of the resin tube will be different in different pulse frequencies, different seasons and test environments. The final test results will be affected to varying degrees, and this type of device can only test a single resin tube at a time, which can easily lead to errors in the detection process.
[0003] Based on the above problems, there is an urgent need for a forklift mast resin pipe life simulation test system that can realize the errors in the final test results caused by the temperature generated by the corresponding work and environmental factors, as well as the quantity during the simulation test.
