Problems solved by technology

There are many inherent defects and deficiencies in the hydraulic drive mode, which are specifically manifested in: ①The seal of the hydraulic system is prone to leakage, the hydraulic oil is easy to pollute the environment, and the problem of waste disposal is even more serious; ②The hydraulic pressure is easily polluted and needs regular maintenance and replacement. High cost; ③It is difficult to improve the accuracy of position control, which requires expensive positioning sensors and precise electro-hydraulic valves. There are creep trends, hysteresis, and blind spots in the movement, and pressure and temperature changes make the control more complicated; ④The role of hydraulic pump source The disadvantage of high noise

Abstract

The invention relates to a device for testing the performance of a shock absorber, specifically an electromagnetically actuated dynamometer. The dynamometer includes a main part I, a control cabinet II connected to the main part I, and a control cabinet II connected to the The upper computer PCⅢ is characterized in that: the main part I uses two symmetrically arranged linear motors as the power source, a linear encoder is used as the position closed-loop control of the linear motor, and a proximity switch is used for the linear motor. The stroke limit control of the motor can meet the high-performance test requirements of shock absorbers of different models. The present invention is obviously superior to the electromagnetic actuated dynamometer with the existing structural mode in terms of precision, installation, maintenance, environmental pollution and noise.

Description

technical field [0001] The invention relates to a device for testing the performance of a shock absorber, specifically an electromagnetically actuated dynamometer. The dynamometer uses a linear servo motor as a power source and adopts an all-position closed-loop motion control method for vibration reduction. The motion control of the shock absorber can meet the high-performance test requirements of shock absorbers of different models. Background technique [0002] At present, the power source of the existing dynamometer in China adopts the hydraulic cylinder drive mode. There are many inherent defects and deficiencies in the hydraulic drive mode, which are specifically manifested in: ①The seal of the hydraulic system is prone to leakage, the hydraulic oil is easy to pollute the environment, and the problem of waste disposal is even more serious; ②The hydraulic pressure is easily polluted and needs regular maintenance and replacement. High cost; ③It is difficult to improve t...
