Abstract
The invention discloses a detecting method on damping force, especially providing a method for transversely testing the damping force of buffer. Wherein, the test process comprises the test on several working positions synchronously; each process comprises: horizontally fixing the buffer on the V-shape block used to positioning; staring the motor, and using hydraulic cylinder to move the piston rod of buffer straight; after several straight motions, the sensor collects the signal into computer; calculating the damping valve of different displacement points; via preset computer program, displaying the relationship between these damping valves and the forces with ordinate to form smooth curve; checking the smoothness of said curve, via checked aberration to find if there is idle range.
Description
Technical field
The present invention relates to a kind of detection method, especially a kind of detection method to damping force.
Background technology
To the big damping force of damper and whether idle running detects, be a great problem both domestic and external how always.At present, what generally use is single station or the vertical checkout equipment of double, and these equipment can satisfy the needs of detection speed height, the detection of vertical system vibration damper.But no matter damper low for relative detection speed, horizontal system is from testing result, still detects the needs that all are difficult to satisfy production and quality requirements on the effect.
Summary of the invention
The objective of the invention is to test the method whether horizontal damping force has idle running in order to provide a kind of.
For realizing purpose of the present invention, this instructions provides a kind of method of transverse test damping force of vibration damper, and its test process is that a plurality of stations detect simultaneously, and each station includes following steps:
On A, the vee-block with vibroshock horizontal fixed to a location usefulness, clamp, the both sides suspension ring adopt the plug assembling;
B, actuating motor, and, make piston lever of reducer do rectilinear motion by the hydraulic cylinder transmission;
C, wait piston lever of reducer are done several straight motions, guarantee that vibroshock left and right sides inner chamber fluid is even;
D, by sensor with signal collection to computing machine;
E, calculate the damping value of different displacement points;
F, show with coordinate system, and connect into smooth curve by the relativeness of computer program with these damping values and power value;
G, check the smooth degree of this curve, by finding whether have distortion phenomenon to determine whether idle running.
This method is simple to operate, changes the method for passing through the circular motion conversion linear motion that crank makees motor in the past, directly by the hydraulic cylinder transmission.The method that damper employing level is installed is all installed an oil cylinder and a sensor on each station, the other end of sensor inserts computing machine.During detection, oil cylinder is done several to-and-fro movements earlier, guarantees that the fluid in the left and right chamber of damper is even, computing machine begins acquired signal by sensor then, draw the damping force value of different displacement points, again the relativeness of these points with the power value is reflected in the coordinate system, connect into smooth curve.By checking the smooth degree of figure on the load-position diagram, whether the phenomenon of distortion is arranged, just whether damper has idle running as can be seen.Because these equipment are by laterally detecting, the conclusion that draws is the state in damper horizontal when system just, has been equivalent to imitate the user mode of damper.Because detection speed is low, inevitably caused the effect that detects lower, this equipment fully takes into account this point just, so the method that has adopted multistation to detect simultaneously.The urceolus of equipment adopts vee-block to support, and the both sides suspension ring adopt the plug assembling, and the time that damper is installed will arrive the shortest, effectively raise effect.
Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Embodiment
With reference to last figure, provide following embodiment.To help to understand the present invention by embodiment, but not limit content of the present invention.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
The method of this transverse test damping force of vibration damper, its test process are that a plurality of stations detect simultaneously, and each station includes following steps:
On A, the vee-block with vibroshock horizontal fixed to a location usefulness, clamp, the both sides suspension ring adopt the plug assembling;
B, actuating motor, and, make piston lever of reducer do rectilinear motion by the hydraulic cylinder transmission;
C, wait piston lever of reducer are done several straight motions, guarantee that vibroshock left and right sides inner chamber fluid is even;
D, by sensor with signal collection to computing machine;
E, calculate the damping value of different displacement points;
F, show with coordinate system, and connect into smooth curve by the relativeness of computer program with these damping values and power value;
G, check the smooth degree of this curve, by finding whether have distortion phenomenon to determine whether idle running.
