Abstract

The invention discloses a mechanical experiment loading device with a two-parameter control. The mechanical experiment loading device comprises a steel wire rope, a fixed pulley, a fixed pulley bearing fixed bracket, a motor, a load control loading part, a displacement control loading part and a belt pulley set, wherein the load control loading part comprises an adjusting extension spring and a force sensor; the displacement control loading part comprises a displacement sensor and a displacement sensor bracket; the steel wire rope gets through the fixed pulley and is connected with the belt pulley set; the fixed pulley is fixed on the fixed pulley bearing fixed bracket; the belt pulley set is connected with the motor; and a load control loading mode and a displacement control loading mode can be adopted. The experiment loading device satisfies requirements such as a large stroke, an extensive frequency application scope, capability of freely switching between the load control and the displacement control, high precision and the like, is convenient to use, low in cost, easy to dismount and move, and convenient to flexibly adjust according to different research needs. The mechanical experiment loading device can be applicable to relevant static, dynamic or fatigue experiments in engineering fields such as aerospace, civil construction, ocean and ships, machinery and the like.

Description

Technical field [0001] The invention relates to an experimental loading device, in particular to a mechanical experimental loading device controlled by dual parameters. Background technique [0002] In many engineering fields such as aerospace, civil engineering, marine and shipbuilding, machinery, etc., various power systems exist widely. When conducting industrial design and scientific research, it is often necessary to carry out experimental research on these systems. The loading device provides an external source of excitation, which is the key and basis for ensuring that the power system can be "moved" according to different requirements. With the progress of industrial technology and the continuous deepening of scientific research, the experimental research of the power system becomes more and more difficult and the parameter range is wider and wider. This puts more stringent requirements on the loading device. [0003] There are mainly the following requirements for the l...
