Problems solved by technology
[0004] The aforementioned known linear reciprocating dynamic testing machine utilizes the acceleration characteristics of the crank-slider mechanism to act on the dynamic sensing device to achieve high G-force (G-force) test conditions. When testing, the vibration of the overall device is quite large, and the machine body will shake too much, which will affect the quality of the test. It is not very ideal, and there is still room for improvement.

A connecting rod dynamic testing machine and testing equipment using the same are disclosed, the machine includes a plummer which is provided with a support block, an active table, a passive table, a parallel four-connecting rods, a test bench and a driving unit. The parallel four-connecting rods each are pivoted on the support block by means of a pivot shaft, the active table and passive table are pivoted on the parallel four-connecting rods, further which are located on opposite sides of the support block. The test bench is located on passive table, and the driving unit so as to drive the active table to progress reciprocating motion, further, the test bench to progress reciprocating motion by means of the parallel four-connecting rods. Therefore, the present invention is capable of reducing noise in operation, and the machine has a simple structure so that the manufacturing cost can be reduced.
Description
technical field [0001] The invention relates to a connecting rod type dynamic testing machine and dynamic testing equipment using the testing machine, especially a connecting rod type three-dimensional dynamic testing machine suitable for testing dynamic sensors and dynamic testing equipment using the testing machine. Background technique [0002] In recent years, with the rapid development of micro-electromechanical systems, various miniaturized, high-performance and low-cost sensors have come out one after another, making the sensor further upgraded from a key component to a main component that generates innovative value, such as: Apple’s iPhone, new Most of the three-axis accelerometers used in iPods and Nintendo Wii are based on micro-electromechanical system technology. The operating principle of the acceleration sensor is to sense the XYZ three-axis components of the acceleration direction, so as to obtain the three-dimensional space of the object. motion vector in . ...
