The work aims to design a test device to simulate the actual service working environment of engineering plastics,and construct the test conditions with the coupling effect of environmental factor erosion and load stress in a multi-type natural environment.The test device for engineering plastics under the synergistic effect of environmental factors and load stress was developed,and the modular design including tensile loading,bending loading,control system and other components was adopted to achieve tensile and bending loads of 0.01～16 Hz loading frequency,with a maximum tensile load of 1 550 kg and a maximum bending load of 375 kg.The developed test device was placed in a multi-type natural environment to apply constant and alternating loads to the test,so as to truly simulate the synergistic effect of environmental factors and load stress in the actual service of engineering plastics.The test device is easy to manufacture and process,with stable and reliable structure,which can be used to evaluate and study the evolution of environmental damage performance of engineering plastics and other types of materials.
