Spring load simulation device with adjustable load

Abstract

The invention discloses a spring load simulation device with an adjustable load, and belongs to the technical field of load simulation. The device comprises load springs, an outer shell, a locking mechanism, a mounting seat, spring sleeves and a spacing rod, wherein the spacing rod is installed in the outer shell; the load spring is independently installed in the outer shell through two spring sleeves sheathed to two ends of the load spring; two spring sleeves are independently a spring sleeve A and a spring sleeve B; the sealing end of the spring sleeve A and the inner end surface of the outer shell are abutted; the sealing end of the spring sleeve B and the end part of the spacing rod in the outer shell are abutted to enable the load springs to be under a compression state; an end wherethe through hole of the outer shell is positioned is fixedly provided with the mounting seat; the piston rod of an actuation-type fire work device penetrates through the through hole of the outer shell to be in contact with the end surface of the sealing end of the spring sleeve A; and when the spring sleeve A moves along the direction of the spacing rod to a proper position, the spring sleeve A is locked through the locking mechanism. By use of the device, testing efficiency can be improved, development expenditure is saved, and development periods are shortened.

Description

technical field [0001] The invention belongs to the technical field of load simulation, and in particular relates to a spring load simulation device with adjustable load. Background technique [0002] The ground performance test is required for the actuating pyrotechnic device in the development stage. The load simulation test bench capable of simulating the force on the wing and the rudder surface is an indispensable equipment. Currently, most of the test benches used are electric loading load simulators and Pneumatic loading type load simulation device. [0003] Electric load simulators and pneumatic load simulators are generally more expensive, depending on the loading principle, the price is 1.5 million to 6 million, and the use and maintenance costs of the above two test benches are relatively high, and a lot of preparation is required before use. Work. Contents of the invention [0004] In view of this, the present invention provides a load-adjustable spring load s...
