Problems solved by technology
[0005] Existing static loaders only meet the precision and controllable loading function of low tonnage (below 10T), and there is a dead zone of precise pressure control in the low load area, which cannot meet the load precision control function of the full load area, and cannot meet the requirements of large tonnage, Precise control of loading requirements for static loads
In addition, the safety control performance of the existing static loading machine is low, which cannot meet the safety control performance required for the static loading simulation of explosive materials

Embodiment
[0068] Such as figure 1 As shown, the specific design of a large-tonnage safe material static accurate loading simulation equipment includes: loader bearing device, load output device, and loading force control device; among them:
[0069] The loading device of the loader is mainly used to transfer the load force of the load output device to the explosive material. Therefore, the mechanical material of the loader's loading device must meet the strength requirements required for loading large-tonnage loads, generally at least according to the load of the weak parts. Four times the redundant design; the load sensor is installed at the bottom of the loading device, and the load sensor should ensure that all loading forces are applied to the load sensor to achieve reliable measurement of the load. At the same time, the loading device and the load output device should be connected reliably. This ensures a smooth, vibration-free load during loading.
[0070] The load output device ...

Description
technical field [0001] The invention relates to the technical field of material static performance testing, in particular to a large tonnage safe material static accurate loading simulation equipment. Background technique [0002] The strength properties of materials are one of the most important indicators of materials as mechanical components. The strength properties of large equipment, military composite materials, and energetic materials are related to the safety of large equipment, the reliability and safety of weapons and equipment. [0003] During the long-life use of anisotropic composite materials, the strength properties change due to various loads such as static loads, high and low temperature loads, fatigue loads, and creep loads. The degradation of strength properties has become one of the most likely problems in the long-life use of materials. [0004] As a kind of anisotropic composite material, the strength of explosive material decreases under static load, ...
