What is the relationship and difference between bolt dynamic torque and static torque?
Anyone who understands the bolt fastening assembly process knows that torque is divided into dynamic torque and static torque. For parts assembly, the dynamic torque is the process input of the engineering R&D department to the manufacturing process. It is not a requirement for the tightening result. The manufacturing process department sets the parameters of the electric tightening gun according to the torque value on the drawing. The peak value displayed on the electric tightening gun at the end of tightening is the dynamic torque.
So the question is, when the electric gun reaches the set torque, how do we know that the bolt or nut has been really tightened and meets the requirements? At this time, the concept of static torque appeared, and regular spot checks should be done during the production process.
For power battery products, this static torque is particularly important. Especially the high-voltage connection part inside the power battery. If the tightening is not in place, it will cause excessive contact internal resistance. During the high-power charging and discharging process of the battery, the contact part will generate a lot of heat. likely to cause thermal runaway. Cause the battery and even the vehicle to burn.
Therefore, the use of dynamic torque and static torque can classify and accurately control torque. The professional explanation of dynamic torque and static torque is as follows:
Dynamic torque is the torque value (range) given by the designer from a technical point of view. Install a dynamic torque transducer on the assembly tool. The peak torque measured by the torque sensor while the bolt is being tightened is the measurement of dynamic torque. For example, the torque at stop set by the electric screwdriver and the fixed torque air trigger and the torque when the preset torque wrench makes a “click” sound after rotating more than 270°.
Static Torque (Static Torque) is the frictional torque when the threaded fasteners in the tightened state continue to be tightened and the rotation between the threaded surfaces has just occurred. To measure, place a direct-reading torque wrench on the freshly tightened fastener. Move smoothly, continuously and evenly in the tightening direction. Apply torque to the torque wrench. until the fastener just begins to turn. The maximum torque indicated during the first few degrees of rotation is a static torque measurement. For example, when using a dial-type torque wrench or a digital-display torque wrench to check the tightening degree of threaded fasteners, memorize the torque indicated by the pointer or the display.
There is a regular mathematical model relationship between dynamic torque and static torque, which varies depending on the connection state. According to statistical laws and years of experience in the automotive industry, the following three relationships are summarized.
a. Soft connection: Static torque is lower than dynamic torque.
b. Hard coupling: Static torque is higher than dynamic torque.
c. Joint joint: Static torque approaches dynamic torque.
The difference between dynamic torque and static torque is mainly in the purpose of measurement. In general, the purpose of dynamic torque measurement is to ensure that the torque during the tightening process is qualified. The purpose of the static torque measurement is to verify whether the dynamic process is subject to variation. At the same time, it ensures the reliability of the clamping force after tightening.
