Abstract

The invention discloses a kind of composite material constant stress exposure test devices, described device includes two frames being correspondingly arranged, wherein experiment collet is provided on a frame, collet is tested to clamp one end of sample, the other end of sample by with the mutually fixed test clamp head clamping of running block connecting portion, running block is connected by rope with the pulley in fixed pulley group, and the connecting portion of fixed pulley group is mutually fixed with another frame.The structure of the present invention is simple, and after sample elongation, no-load voltage ratio is constant, and load is constant；Pulley blocks no-load voltage ratio scope is bigger；And minimum dead load can be reduced effectively.

Description

A kind of composite material constant stress exposure test device
Technical field
The present invention relates to a kind of experimental rigs of constant stress.
Background technology
Traditional composite material constant stress exposure test device is as shown in Figure 1, the steelframe being used to support including one, in steel It is hinged there are one extension obliquely and then an again horizontal-extending lever on frame, the end of lever is provided with counterweight, sample Between the head of the horizontal segment of lever and steelframe.
Counterweight generates a dead load by lever to sample, and the size of entire loading force is：
F=GZ+K1×Mg
Wherein, GZThe pulling force generated in the horizontal direction for lever itself；Mg is counterweight weight；K1For lever no-load voltage ratio.
After the sample elongation of such experimental rig, lever loses level, no-load voltage ratio K1Variation is generated, load is no longer constant；Thick stick Bar cannot be too long, and otherwise rigidity declines bending, causes no-load voltage ratio K1It is too small, generally 3 to 6；Lever cannot be too heavy, otherwise GZIt is too big, Smaller dead load cannot be loaded, general below 20Kg cannot be loaded.
The content of the invention
The object of the present invention is to provide the composite material constant stress exposure test devices that a kind of no-load voltage ratio is kept constant.
To achieve these goals, using following technical scheme：A kind of composite material constant stress exposure test device, it is special Sign is：Described device includes two frames being correspondingly arranged, and is provided with experiment collet on a frame wherein, tests collet One end of sample is clamped, the other end of sample by with the mutually fixed test clamp head clamping of running block connecting portion, running block It is connected by rope with the pulley in fixed pulley group, the connecting portion of fixed pulley group is mutually fixed with another frame.
The end of the rope is connected with counterweight, and counterweight is in movement in vertical direction.
The structure of the present invention is simple, and after sample elongation, no-load voltage ratio is constant, and load is constant；Pulley blocks no-load voltage ratio scope is bigger； And minimum dead load can be reduced effectively.
Description of the drawings
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the structure diagram of the embodiment of the present invention.
Specific embodiment
The present invention is described further with reference to the accompanying drawings and detailed description.
As shown in Fig. 2, a kind of composite material constant stress exposure test device, described device includes two frames being correspondingly arranged Frame is provided with experiment collet wherein on a frame, experiment collet clamps one end of sample, and the other end of sample is by with moving The mutually fixed experiment grips of pulley blocks connecting portion, running block are connected by rope with the pulley in fixed pulley group, fixed The connecting portion of pulley blocks is mutually fixed with another frame.The end of the rope is connected with counterweight, and counterweight is in movement in vertical direction.
The shortcomings that being loaded using pulley blocks, overcoming original device, the size of loading force are：
F=GZ+K1×Mg
Wherein, GZThe pulling force generated in the horizontal direction when not adding counterweight for running block and fixed pulley group, if device It can keep fully horizontal, then this is zero；Mg is counterweight weight；K1For pulley no-load voltage ratio.
After such design, after sample elongation, no-load voltage ratio K1Constant, load is constant；Pulley blocks no-load voltage ratio K1Up to 5 to 30； And minimum dead load is up to 1Kg.
