The invention provides a continuously adjustable spring load simulator. The continuously adjustable spring load simulator comprises a force arm pivot and a force arm limit screw; the number of linearsliding rails is 2, one of the linear sliding rails is engraved with equivalent stiffness scale lines and numbers, which are fixed to an inner upper top surface of an installation frame; the number ofsliders is 2, and the sliders are mounted on the two linear guide rails respectively; L-shaped carrier plates are mounted on the lower surfaces of the sliders; and the force arm pivot passes throughthe right end of a force arm to be fixed on a lower left portion of the installation frame. The continuously adjustable spring load simulator is easy to manufacture, is low in cost, and can be used asa load simulator in the fatigue test equipment of small load parts such as operating rods and steel wire cables. In the process of setting test conditions, the continuous adjustment of the equivalentstiffness of the load spring is realized, the test preparation time is saved, the modification or replacement of the spring is avoided, the operability is strong, and the upper and lower limits of the load can simultaneously meet the requirements of test regulations.
Description
technical field [0001] The invention belongs to the technical field of mechanical testing, and more specifically relates to a continuously adjustable spring load simulator. Background technique [0002] The spring load simulator is used in fatigue test equipment for small load parts such as operating rods and steel wire cables. It is used as a load simulator to test the load performance and fatigue life of small load parts. It is widely used in automobiles, construction machinery and other manufacturers and manufacturers. Laboratory in the mechanical field. [0003] Based on the above, the inventors have found that the current commonly used spring load simulator has the following deficiencies: [0004] 1. The stiffness of the spring (equivalent) in the load simulator cannot be continuously adjusted, and the stiffness of the spring load simulator can only be changed by means of: increase, decrease, series, parallel and replacement, and the adjustment process is cumbersome; ...
