Description

technical field [0001] The invention relates to a motion generating device, in particular to a stable dynamic linear motion generating device. It belongs to the technical field of motion parameter traceability. Background technique [0002] Linear motion is one of the common motion states. In national defense, military, industrial production and daily life, there is a need to measure the state parameters of linear motion. For example: during the missile launch process, the velocity and acceleration of the inner ballistic exit barrel (missile launch barrel / box) are important parameters for judging whether the performance of the launch system is normal and whether the launch process is successful or not. In the steel rolling production line, the speed monitoring of the steel billet entering the furnace can reduce the scrap rate, thereby reducing the production cost, optimizing the production process, predicting and eliminating hidden troubles. Many special engineering applic...

Problems solved by technology

The vibrating table can only produce small displacement and low-amplitude vibration, the motion stroke is short, the speed amplitude is small, and it cannot simulate most linear motion states; the air cannon uses the principle of aerodynamics, the working medium is air, and is composed of a differential pressure device and an automatic control device. The rapid exhaust valve can instantly convert the air pressure energy into the air jet kinetic energy, which can produce a strong impact force. The equipment is bulky, and the moving target is destroyed after being launched. It is impossible to install other sensors on it, and the cost is relatively high. There is a certain risk; the drop device can only provide a free fall process, and the form is single; the collision device uses the mechanical collision of objects to generate impact motion, the controllability is poor, and the energy recovery form is complicated in a limited space

To sum up, the current linear motion generating device has disadvantages such as single parameter, poor controllability, high cost or low safety factor.
