Abstract

The invention discloses a manufacturing method with elastic energy of an elastic hinge brake gradually released. According to the technical scheme, the elastic energy of the elastic hinge brake is controlled to be released by the aid of a material with viscoelasticity and shear thickening property at a high temperature, so that the structure is gradually unfolded, then excessive impact in the unfolding process is avoided, the material with viscoelasticity and shear thickening property at the high temperature is hardened at the room temperature, the elastic energy of the elastic hinge brake canbe frozen, the shape is fixed, after the temperature rises to the transition temperature (>60 DEG C) of a polymer material or above, the material becomes soft and the elastic energy is released, meanwhile, due to the viscoelasticity and the shear thickening property of the material at the high temperature, the elastic energy can be controlled to be gradually released, so that the occurrence of impact behaviors is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of unfolded structures, and in particular relates to a manufacturing method of an elastic hinge brake whose elastic energy is gradually released. Background technique [0002] The elastic hinge and the elastic brake are often accompanied by impact during the structural expansion process, and this impact will bring certain dangers, which brings inconvenience to use. How to reduce or avoid the impact behavior during the unfolding process of the structure has always been one of the factors considered in the structural design. Generally, a spring is added to make a spring hinge; or a damping hinge is designed by using the damping effect, so as to effectively avoid impact, but this damping hinge has the disadvantages of complex device and large volume. [0003] In recent years, in terms of anti-shock effect, the use of shear thickening principle of materials as an effective means of anti-shock has been used more...
