Abstract

The invention discloses a dynamic load simulation test device. The device comprises a work bench. The work bench is installed with a tested object support, a torque sensor support, a servo commutator support, a servo motor support and an acceleration sensor support. The tested object support is installed with a tested object. The tested object is connected to a torque sensor through a first shaft coupling. The torque sensor is installed on the torque sensor support. The torque sensor is connected to a servo commutator through a second shaft coupling. The servo commutator is installed on the servo commutator support. The servo commutator is connected to a servo motor and an acceleration sensor through a third shaft coupling and a fourth shaft coupling. The torque sensor, the servo motor and the acceleration sensor are connected to a test and control system. In the invention, through controlling one servo motor, a plurality of load forms of a dynamic inertia load and a dynamic torque load can be simultaneously simulated, a condition that a traditional inertia load and a torque load control simulation respectively is replaced, and experiment cost and a land occupation space are reduced.

Description

technical field [0001] The invention relates to a dynamic load simulation test device and a test method, belonging to the technical field of mechanical experiments. Background technique [0002] Load simulation technology refers to simulating the load force or moment of the loading object through certain technical means under laboratory conditions. It is an emerging semi-physical simulation and test technology. In the research and testing of new products and new technologies, load simulation technology overcomes the limitation of using actual loading objects in the actual environment. The research program and system model can also be realized through the hardware-in-the-loop load simulation platform. Especially in some fields such as aerospace and marine engineering, which are not easy to carry out online testing, load simulation technology is even more important.
