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 vibratio
