[0002] In the design and development process of various carriers (such as cars, motorcycles, bicycles, etc.), the mechanical performance parameters of the carrier are the parameters that need to be considered in the design stage and tested in the verification stage, for example, the appearance aerodynamics, motion posture, starting speed, acceleration speed, deceleration speed, etc. of the carrier, at this time, the corresponding motion measuring instrument needs to be installed on the carrier to collect data. The quality, size and internal structure of the measuring instrument itself will introduce errors to the collected data to a certain extent, and the maximum elimination of data errors can play a positive role in design analysis.
[0003] Among them, the data collection in terms of acceleration and carrier posture often needs to be filtered. Currently, adding a filter structure on the physical layer is the most efficient and easy to implement. However, the filter structure on the physical structure will introduce new uncertainty factors in terms of aerodynamics and acceleration collection. Secondly, the exposed filter structure will damage the overall appearance of the instrument and reduce the aesthetic level. For example, the mechanical structure of the filter exposed in the test environment will increase the resistance of the test object to a certain extent, and the complex characteristics of fluid analysis will make it difficult to offset the error with mechanical deviation. In addition, the unattractive appearance affects the acceptance of the instrument by the user. In other fields, it is common to use flexible materials for physical high-frequency filtering of sensors, but low-frequency, large-amplitude structural design is currently less common.
