Problems solved by technology
[0004] The roller support in the test device not only bears the weight of the viscous damping cylinder, but the load used to balance the overturning moment far exceeds the self-weight of the damping cylinder, and the friction of motion will inevitably bring deviations to the test data of the horizontal damping force

Embodiment
[0027] Example: the horizontal offset of the viscous damping cylinder is 20 mm, the length of the central screw swing section of the suspension damping cylinder top plate and the piston barrel exceeds 1000 mm, and the top plate lifting point is 0.2 mm up and down when swinging, which will not cause the viscous damping cylinder top plate severely tilted;
[0028] The horizontal damping force of the viscous damping cylinder is generally 50KN smaller than the vertical damping force, so the horizontal characteristic test of the viscous damping cylinder can be carried out on the 50KN hydraulic damper test bench to realize the sharing of the test bench;
[0029] The damping characteristics of a viscous damping cylinder generally follow the following formula:
[0030] F=CV α
[0031] where F is the damping force
[0032] C is the damping coefficient
[0033] V is the moving speed
[0034] α is the speed index
[0035] Apply different moving speeds V to a viscous damping cylinde...

The clampingapparatus for detecting the horizontal performance of the viscous damping cylinder has the advantages that the test device is arranged on the outer surface of the machine frame, the test device comprises the bottom support plate, and the outer surface of the machine frame is fixedly connected with the back surface of the bottom support plate, so that the clamping apparatus has the characteristicsthat the friction resistance when the viscous damping cylinder receives horizontal force is reduced to the minimum by the test device; the position of the horizontal force on the viscous damping cylinder can be conveniently regulated; the structure of the viscous damping cylinder can be conveniently improved; the detection precision is improved; and the horizontal damping characteristics in different horizontal positions can be detected.
Description
technical field [0001] The invention relates to the technical field of performance and quality detection of a damping device for vibration reduction and vibration isolation of equipment and pipelines, and more specifically relates to a tool fixture for horizontal performance detection of a viscous damping cylinder. Background technique [0002] The horizontal motion testing device of the viscous damping cylinder provided in the relevant literature places the viscous damping cylinder on the roller support, the cylinder body is connected with the load cell, and the force brake is connected with the top plate of the damping cylinder. [0003] The force line of the force brake and the force line of the load cell are not on the same straight line, which will generate an overturning moment to the viscous damping cylinder. Therefore, a roller support is set at the lower edge of the top plate to balance the overturning moment and prevent the piston cylinder from tilting. [0004] Th...
