Description

technical field [0001] The invention relates to a loading test device, in particular to an elastic drive test stand and its application method. Background technique [0002] Before all kinds of engineering equipment and products are put into use, many of them need to be tested for rotational loading and linear loading. [0003] Existing rotary loading devices and equipment, such as motor-driven rotary loading devices, generally achieve rotary loading by controlling the driving motor; if the angular velocity changes greatly in a short period of time and the accompanying torque changes greatly, very precise control is required system, and consume a lot of energy during use; the cost of such equipment, use cost and maintenance cost are generally high, which undoubtedly pushes up the cost of the product, especially for a small number of products that must be produced and tested. class device components. [0004] Existing linear loading devices and equipment, such as hydraulic ...

Problems solved by technology

[0003] Existing rotary loading devices and equipment, such as motor-driven rotary loading devices, generally achieve rotary loading by controlling the driving motor; if the angular velocity changes greatly in a short period of time and the accompanying torque changes greatly, very precise control is required system, and consume a lot of energy during use; the cost of such equipment, use cost and maintenance cost are generally high, which undoubtedly pushes up the cost of the product, especially for a small number of products that must be produced and tested. class device component

[0004] Existing linear loading devices and equipment, such as hydraulic actuators, are expensive, costing tens of millions; and consume a lot of energy during use, resulting in high maintenance costs; in addition, the peak speed of such equipment is generally relatively high Small, many of which do not exceed 1m / s; and for impact devices with instantaneous high-speed loading such as Hopkinson rods, it is difficult to achieve high-speed and long-term loading, and it is impossible to simulate the high-speed loading process for a period of time, and there is also equipment construction cost , Use cost, high maintenance cost
