Abstract
The invention provides a motor vehicle spring testing device and method, in order to truly reflect the service life of a motor spring in a real usage environment. The testing device comprises a base and a vibration rack mounted on the base. The base is provided with a first fixing part. The vibration rack is provided with a second fixing part. An excitation source of the vibration rack is connected with a control unit. The control unit pre-stores road spectrum data or is provided with a mechanism for reading the road spectrum data. The motor vehicle spring testing method comprises the following steps of A, obtaining the motor vehicle spring testing; B, using the first fixing part and the second fixing part to fix two ends of a to-be-tested spring; and C, the control unit controlling the excitation source according to the road spectrum data so as to enable the vibration condition of the vibration rack to accords with the road spectrum data. In the abovementioned test, the vibration of the vibration rack is controlled by the road spectrum data, so as to enable the vibration condition of one end of the spring is identical to the condition of a real road surface, so that the authenticity in testing is greatly improved, and the testing result is enabled to be persuasive.
Description
Technical field
The invention belongs to spring technical field of measurement and test, be related specifically to a kind of automobile-use spring proving installation and method of testing.
Background technology
Current spring test is all the compression and tension concentrating on spring, and the simplest method utilizes the devices such as cylinder to carry out tension and compression repeatedly to spring.Some characteristics of spring can be tested out although it is so, but due to this kind of test environment different from practical service environment, the cogency of therefore testing is also little.Give an example, automobile-use spring uses under the environment of automobile bumpiness, and its amplitude of jolting, direction etc. are all relevant to the road surface of automobile actual travel, and traditional test reckon without the surface conditions of automobile actual travel.
Summary of the invention
The object of the invention is to propose a kind of automobile-use spring proving installation and method of testing, to reflect the life-span of automobile-use spring under practical service environment truly as far as possible.
Automobile-use spring proving installation of the present invention comprises base and by the vibrating grid of support installing on base, described base is provided with the first fixed part, and described vibrating grid is provided with the second fixed part; The driving source of vibrating grid is connected with a control module, and described control module prestores road modal data or is provided with the mechanism that can read road modal data.
The automobile-use spring method of testing applying above-mentioned automobile-use spring proving installation comprises the steps:
A: obtain road modal data;
B: utilize the first fixed part, the two ends of spring to be measured fix by the second fixed part;
C: control module controls driving source according to road modal data, makes the Vibration Condition of vibrating grid conform to road modal data.
In above-mentioned test, controlled the vibration of vibrating grid by road modal data, make the Vibration Condition of spring one end identical with the situation on actual road surface, thus substantially increase the authenticity of test, make test result more convincing.
Further, the height adjustable of described support.In the step B of method of testing, after fixing spring to be measured, the height of adjusting pole, make the original state of spring to be measured identical with the original state of actual service condition, such as, say, if on spring fitting to be measured to vehicle body time, be in compressive state, so will reduce the height of support, such vibrating grid will apply certain pressure to spring to be measured, makes spring to be measured also be in compressive state; Otherwise the height of support will be improved, repeat no more herein.By simulating the installment state of spring to be measured, the authenticity of test can be improved further.
Specifically, described driving source is cylinder, and control module, by the Vibration Condition of control cylinder, controls the vibration vibrating house.
Automobile-use spring proving installation of the present invention and method of testing can be tested spring by Reality simulation surface conditions, thus reflect the life-span of automobile-use spring under practical service environment truly as far as possible, have good practicality.

Embodiment 1:
As shown in Figure 1, the automobile-use spring proving installation of the present embodiment is comprised base 1 and is installed on the vibrating grid 3 on base 1 by adjustable for height support 2, and described base 1 is provided with the first fixed part 4, and described vibrating grid 3 is provided with the second fixed part 5; The driving source of vibrating grid 3 is connected with a control module, and described control module prestores road modal data or is provided with the mechanism that can read road modal data.
The automobile-use spring method of testing applying above-mentioned automobile-use spring proving installation comprises the steps:
A: obtain road modal data;
B: utilize the first fixed part 4, second fixed part 5 to be fixed at the two ends of spring to be measured, the then height of adjusting pole 2, makes the original state of spring to be measured identical with the original state of actual service condition;
C: control module controls driving source according to road modal data, makes the Vibration Condition of vibrating grid 3 conform to road modal data.
In above-mentioned test, controlled the vibration of vibrating grid 3 by road modal data, make the Vibration Condition of spring one end identical with the situation on actual road surface, thus substantially increase the authenticity of test, make test result more convincing.
