The quality of bolt assembly and the precision of bolt tightening are crucial elements in the entire process of automobile assembly. This article delves into the significance of the bolt tightening process during vehicle assembly and its mechanical analysis. Understanding the importance of this process is essential for ensuring the structural integrity and safety of automobiles.
Mechanical Analysis of Bolt Tightening:
During the bolt tightening process, bolts undergo stretching and deformation due to tensile forces while engaging in a compressive interaction with connectors through threaded fasteners. The forces applied to the bolts and connectors are equal in magnitude and opposite in direction.
At this stage, the force exerted by the bolt on the connected part is referred to as the axial preload of the bolt. The force changes in several stages during bolt tightening. Initially, when the bolt head does not make contact with the fastener, compression force is zero, and torque is minimal.
As the bolt head aligns with the fastener, further tightening leads to a gradual increase in compression force and torque. Continued tightening results in the compression force and torque reaching a plateau, as the bolt nears its yield point. Once this yield point is reached, further tightening leads to reduced tightening force and torque, potentially causing deformation or fracture of the bolt.
Bolt Tightening Methods:
Three primary bolt tightening methods are used in automobile assembly:
Torque Control Method:
This method relies on the linear relationship between axial clamping force (F) and tightening torque (T), expressed as T = K * F.
It is cost-effective, utilizing a torque wrench for quality checks.
However, it may lack precision and is susceptible to environmental factors.
Torque Angle Control Method:
This method involves initial tightening to a fraction (typically 40% to 60%) of the full torque, followed by tightening to a specified angle.
It provides high control precision and generates substantial axial clamping force.
The downside is the complexity of the control system and the need for precise measurement of pre-tightening torque and angle.
Yield Point Control Method:
This method tightens bolts until they reach their yield point.
It ensures reliable clamping force but requires careful monitoring to prevent over-tightening.
Dynamic Torque vs. Static Torque:
Dynamic torque is measured during the tightening process, ensuring that the axial preload meets engineering requirements.
Static torque, measured after tightening, is used to monitor production process stability.
Tool Selection for Bolt Tightening:
Tool selection is influenced by production capacity, assembly complexity, and assembly process layout.
The decision between power tools and manual tools is based on actual assembly needs and the complexity of the product.
Early planning and design of the bolt tightening process are essential to prevent assembly abnormalities and enhance product quality.
Conclusion:
Bolt tightening is a critical aspect of automobile assembly, impacting structural integrity and safety. Properly executed bolt tightening ensures the stable operation of the production line, improves economic benefits, and enhances product quality while reducing development costs. Understanding the mechanics of bolt tightening and selecting the appropriate tools are pivotal for achieving these goals in the automotive assembly process.

Bolts are ubiquitous in both industrial production and daily life. The performance grade of bolts, particularly in steel structure connections, encompasses a range of more than ten grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, and others.
Bolts rated 8.8 and above are crafted from low carbon alloy steel or medium carbon steel and undergo heat treatment processes like quenching and tempering. These are generally referred to as high-strength bolts, while the remainder are termed ordinary bolts.
The Principle of High-Strength Bolt Connections
High-strength bolt connections offer several advantages, including straightforward assembly, robust mechanical performance, disassembly capability, resistance to fatigue, and stability under dynamic loads.
The high-strength bolt connection process involves tightening the nut with a specialized wrench to generate substantial and controlled pre-tension in the bolt. This pre-tension is transmitted uniformly to the connected components through the nut and backing plate. Under the influence of this pre-tension, a substantial frictional force arises along the surfaces of the connected components. As long as the axial force remains below this frictional force, the components will not slip, and the connection remains intact. This forms the fundamental principle of high-strength bolt connections.
Distinguishing High-Strength Bolts from Ordinary Bolts
1. Material Difference
High-strength bolts can bear greater loads than their ordinary bolt counterparts of the same specification, primarily due to differences in material strength.
Ordinary Bolts: These are typically composed of Q235 (A3) material.
High-Strength Bolts: High-strength bolts are manufactured from high-quality materials, such as 35# steel or other superior materials. Following fabrication, they undergo heat treatment to enhance their strength.
2. Strength Level Difference
High-strength bolts come equipped with higher strength levels compared to ordinary bolts.
High-Strength Bolts: Commonly utilized grades include 8.8s and 10.9s, with 10.9 being the more prevalent choice.
Ordinary Bolts: Ordinary bolts exhibit lower strength levels, typically ranging from 4.4, 4.8, 5.6 to 8.8.
3. Stress Characteristics Difference
The stress distribution and transfer mechanisms vary between high-strength bolts and ordinary bolts.
High-Strength Bolts: High-strength bolts operate by inducing pre-tension and transferring external forces through friction. In addition to their superior material strength, high-strength bolts generate significant pre-tension forces, resulting in the compression of connecting members and the creation of substantial friction forces perpendicular to the screw direction.
Ordinary Bolts: Ordinary bolt connections rely on the shear strength of the bolt rod and the pressure against the hole wall to transmit shear forces. When the nut is tightened, the pre-tension generated is minimal and can be disregarded in its impact.
4. Usage Perspective
The choice between high-strength bolts and ordinary bolts depends on the specific application and structural requirements.
High-Strength Bolts: High-strength bolts are commonly employed for critical components in building structures. They are often used for permanent connections, with two primary types—friction-type, applied with torque wrenches to achieve specified pre-stress, and pressure-type, which are unscrewed using special tools.
Ordinary Bolts: Ordinary bolts, with their lower shear performance, find application in secondary structural components. These bolts only require tightening and can be reused. Conversely, high-strength bolts are not reusable due to their pre-stressed nature.
