Abstract

The invention relates to a glove palm vibration transmissibility measurement and evaluation device and method. The device comprises a measurement handle assembly, a vibration table, a power amplifier, a vibration controller, a data acquisition analyzer and a computer. The method is high in measurement precision, the computer sends a vibration command to the vibration controller, so that the vibration controller outputs a control signal to the power amplifier through the output channel, the power amplifier converts the control signal into current for driving the moving coil of the table body, and the three-axis acceleration sensor in the handle can receive a vibration excitation signal generated by the vibration table. A vibration signal is output to an input channel of the vibration controller, the vibration controller collects the vibration signal, compares the vibration signal with an internal reference value, adjusts a vibration control signal and transmits the vibration control signal back to the vibration table, measurement is started when the measurement requirement is met, and the computer displays the grip strength and the feeding force of the handle in real time. The collected data is displayed according to needs, data analysis and processing are carried out according to requirements, and a measurement and evaluation report of the vibration transmissibility of the palm part / vibration material of the glove is formed.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration and impact hand-transmitted vibration, and in particular relates to a measuring and evaluating device and a measuring and evaluating method for the vibration transmissibility of a glove palm. Background technique [0002] Occupational diseases in my country are divided into 10 categories and 132 kinds, among which arm vibration disease is the fifth item in the sixth category of occupational diseases caused by physical factors. The prevention of arm vibration disease, in addition to avoiding or reducing the operation of vibration equipment as much as possible, the most important prevention method is that the operator wears anti-vibration gloves with excellent anti-vibration performance. [0003] As early as 2002, my country has promulgated and implemented the national standard GB / T 18703-2002 "Measurement and Evaluation of the Vibration Transmittance of the Palm of Gloves". However, s...
