Abstract

The invention discloses an energy accumulation type high-speed and high-acceleration tester which is particularly suitable for a field needing to reach a high-speed test in extremely short time. The tester is characterized by comprising a high-speed main engine part, an energy accumulation driving and clutching part and an axial vibration absorption and acceleration part. By using a driving manner of combining an energy accumulation mechanism with a static abrasion eliminating mechanism, an energy accumulation motor can drive an energy accumulation flywheel group (comprising a friction wheel) to a certain range above a target rotary speed and then an axial vibration absorption and acceleration mechanism is rapidly pressed, so that instant acceleration can be realized by energy and rotary speed transmission; and main energy and friction energy are provided for a test piece part, and an auxiliary motor provides initial static abrasion eliminating energy.

Description

technical field [0001] The invention relates to an energy-storage type high-speed and high-acceleration testing machine, which is especially suitable for occasions requiring high-speed testing in a very short time. Background technique [0002] For some centrifugal tests or high-speed test pieces for other purposes, it is often required to reach 4000-5000rpm, or even higher. In the case that no additional time is required, the power requirement for the motor is not the main contradiction, but for simulating special working conditions, sometimes a very short additional time is required. At this time, for the test piece that is not too large, the motor power The requirements will rise rapidly. For example, the driving power of a 20kg test piece may require the motor power to reach hundreds of megawatts and the output torque to reach thousands of Nm. At present, it is difficult to achieve, and even if it is barely achieved, the cost is extremely high. Contents of the inventio...
