Problems solved by technology
When designing the vibration fixture, according to the length of the sensor in different situations, it is divided into three types of vibration fixtures: long, medium and short. The installation base of the vibration table on the vibration table is inconsistent with the requirements of each model host. If each sensor makes a vibration fixture, the type of sensor in the factory There are eight or nine hundred kinds, and the production cost of the vibrating fixture will be a very large expense, the production cycle is long, and the storage workshop does not have such a large space

Description
technical field [0001] The invention relates to the technical field of oil quantity sensor vibration test, in particular to a general auxiliary test device for oil quantity sensor vibration test. Background technique [0002] Vibration test is an essential environmental test item before product finalization. The purpose of the vibration test is to do a series of controllable vibration simulations in the test, to test whether the product can withstand the test of transportation or vibration environmental factors during the life cycle, and to determine the required standards for product design and function. According to statistical data, improving the design level by 3% will increase recycling by 20% and reduce unnecessary expenditures by 18%. There are different methods for vibration simulation according to different purposes, such as resonance search, resonance dwell, cyclic scanning, random vibration and stress screening, etc. Vibration test is an important part of enviro...
