Based on a new proposed parallel type six-axis acceleration sensor structure

mathematical model for sensitivity is constructed from the forward dynamics equation of system

and mapping relationship between the sensor sensitivity and structural parameters is deduced. Based on ADAMS software

the sensor is parameterized modeling and the sensitivity is optimized. The simulation value are compared with the results of theoretical calculation

and the correctness of the mathematical model is verified. The results show that the sensitivity of linear acceleration is mainly affected by the mass of the mass-block

and the angular acceleration sensitivity is affected by the mass of the mass-block and side length of the mass-block

and regardless of the size of the housing. The sensitivity of linear acceleration and sensitivity of angular acceleration in three orthogonal directions of the space satisfy the isotropy.
