Design theory of a two-bore flat-beam force transducer
I. Introduction. With the continuous development of industrial automation and intelligence, the requirements for sensor technology are also increasing. As an important type of sensor, force sensors are widely used in various engineering fields. Among them, the double-bore flat beam force sensor has attracted extensive attention due to its unique structural design, high measurement accuracy and stability. This article will provide an in-depth study of the design theory of double-bore flat beam force transducers.
2. Structural design of double-hole flat beam force sensor.
The two-bore flat beam force transducer is mainly composed of an inductive beam, two stress plates and an upper and lower base. The induction beam is made of high-strength materials and has good elastic properties. In the middle of the induction beam, there are two holes perpendicular to each other for the installation of stress sheets. A stress plate is a kind of electrical strain gauge, when the induction beam is subjected to an external force, the stress plate will produce strain along with it, thus changing its resistance value. The function of the upper and lower bases is to fix the induction beam and transmit external forces.
3. The design principle of the double-hole flat beam force sensor.
The design principle of the two-bore flat beam force transducer is based on the theory of elastic mechanics and resistance strain. When the induced beam is subjected to an external force, the stress sheet will be stretched or compressed due to the bending deformation of the beam, thus changing its resistance value. By measuring the change in the resistance value, the magnitude and direction of the external force can be derived. Specifically, by measuring the change in the resistance value of the two stress sheets, the force components in the x and y directions can be calculated, and thus the magnitude and direction of the resultant force of the external force can be obtained.
Fourth, the optimal design of the double-hole flat beam force sensor.
In order to improve the measurement accuracy and stability of the two-bore flat beam force transducer, an optimized design is required. First of all, the material selection of the induction beam is very important, and it is necessary to choose a material with high elastic modulus, low coefficient of thermal expansion, and good corrosion resistance. Secondly, the cross-sectional shape and size of the induction beam need to be designed according to the actual needs to meet different measurement ranges and accuracy requirements. In addition, the process of attaching the stress plates is also a key factor affecting the performance of the sensor. It is necessary to select strain gauges with high sensitivity, low hysteresis and long-term stability, and adopt scientific pasting process to ensure the consistency and reliability of the sensor.
5. Application prospect of double-hole flat beam force sensor.
As a type of force transducer with high precision and high stability, double-bore flat beam force transducers are widely used in various engineering fields. For example, in the field of automobile manufacturing, double-hole flat beam force sensors can be used to accurately measure engine cylinder pressure, braking system torque, etc., to improve the safety and reliability of automobiles. In the field of intelligent manufacturing, double-hole flat beam force sensors are also widely used in the force control of robot arms and the cutting force monitoring of CNC machine tools. With the continuous development of industrial automation and intelligence, the application prospect of double-hole flat beam force transducer will be broader.
VI. Conclusions.

As a type of force transducer with high precision and high stability, the double-bore flat beam force transducer has a wide range of application prospects. In order to make the most of its advantages, it is necessary to continuously optimize the design to improve the measurement accuracy and stability of the sensor. In the future, with the continuous development of new materials, new processes and new technologies, the performance of double-hole flat beam force sensors will be further improved, making greater contributions to the development of industrial automation and intelligence.
