Magnetic disk damper damping effect test method

Abstract

The invention provides a magnetic disk damper damping effect test method. An onboard unit is placed on a vibration platform, a sensor is connected onto the onboard unit and a hard disk box damping structure respectively, and in test, software is used to test an IO access rate of the hard disk box. The method mainly comprises the following steps: (1) vibration test conditions are set, test conditions are combined for test, and the IO access rate under each combined vibration test condition is recorded; and (2) the number of blocks with different I / O access times is counted, the I / O access condition under a different vibration condition is acquired, and the damping effects of the damping structure of the hard disk under the different vibration condition are further acquired. Through carryingout data analysis on the IO access rate under a different vibration test condition, the damping effects of the damping structure of the hard disk under the different vibration condition can be acquired, the damping structure of the hard disk under the different condition is further improved, and in a different geographical region, a different damping structure is used.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for the vibration reduction effect of a disk shock absorber. Background technique [0002] For the vibration reduction effect test of the vehicle-mounted machine, the general detection method is: place the vehicle-mounted machine on the vibration platform according to the vibration standard: (1) The sensors are respectively connected to the vibration-damping structure of the vehicle-mounted machine equipment and the hard disk box, and the sensor collects The process data of each vibration frequency, analyze two sets of data to determine the effect of vibration reduction; (2) When the vibration is over, check whether the stored data is continuous or lost; by using this method to confirm whether the designed vibration reduction is effective. However, the current detection method has the following defects: (1) It is a macro result to determine the vibration reduction effect through the...
