dim springs are mechanical energy storage structures, primarily used in ancient ballistae and other crossbow-type weapons. Torsion springs store energy by twisting or rotating elastic materials that are soft and highly tough, thereby imparting a certain amount of mechanical energy to the projectile. Modern torsion spring torque bars are mostly made of steel with good elasticity, and their forms have varied greatly; examples include the hairsprings in mechanical watches, power springs in toy gyro guns, and torque bars in tanks and automobiles. Torque bars are compact yet provide high torque, making them ideal as shock absorption components for transportation vehicles.

dim spring mechanical principles

Ring springs consist of outer rings with inner conical surfaces mating with inner rings with outer conical surfaces. The number of outer ring pairs is determined by the magnitude of the load and deformation requirements. Ring springs are commonly used in applications where space is limited but strong buffering is required. A ring spring comprises many pairs of inner and outer rings; if damaged or worn, it is not necessary to replace the entire assembly, only the individual discarded rings need to be replaced, making repair easier and more economical. Due to the significant friction on the contact surfaces when the outer and inner rings slide relative to each other along the mating cones, the axial force during loading is balanced by surface pressure and friction. This effectively reduces the effect of the axial load, i.e., increases the spring stiffness. During unloading, friction hinders the recovery of the spring's elastic deformation, thus effectively reducing the spring force. The characteristic curve of a ring spring during one loading and unloading cycle is OABO; without the effect of friction, it would be OC. During unloading, the characteristic curve starts from point B rather than point E, which is due to the reduction caused by elastic hysteresis of the spring. Ring spring: A spring composed of alternating stacked washer-like spring steel rings with inner conical and outer cylindrical surfaces, and washer-like spring steel rings with inner cylindrical and outer conical surfaces. The number of pairs of inner and outer rings in a ring spring is determined based on the magnitude of the load it bears and the deformation requirements.

dim spring structure and principles

A torsion bar spring itself is a torsion bar made of spring steel. The cross-section of the torsion bar is typically circular, with fewer instances being tubular or rectangular. Its ends can be shaped as splines, squares, hexagons, or cylinders with flat surfaces, allowing one end to be fixed to the vehicle frame and the other to the suspension arm, which is connected to the wheel. One end of the torsion bar spring is fixed to the frame, and the other end is connected to the wheel via the suspension arm. When the wheel encounters an obstacle on the ground and jumps upward, the wheel drives the suspension arm to rotate around the torsion bar axis by a certain angle, causing the torsion bar to undergo torsional deformation (elastic deformation). Meanwhile, the elastic potential energy stored by the torsional deformation of the torsion bar is released when the wheel leaves the obstacle, allowing the force transmission mechanism and the wheel to return to position quickly. During manufacturing, a permanent torsional deformation is pre-applied to the torsion bar to introduce a certain prestress. The direction of this pre-applied torsion is the same as the direction of torsion when the bar is installed and operating in the vehicle, with the aim of reducing actual stress during operation and extending service life. Note that left and right torsion bars are not interchangeable.

dim spring functions and applications

1) Reset function: The spring deforms under external force and returns to its original state once the force is removed. Many tools and devices utilize this property of springs for resetting. For example, reset springs are installed on the hinges of many building entrance doors, allowing the door to automatically return to its closed position after people pass through. This function is also used in products such as automatic umbrellas and mechanical pencils, offering great convenience. In addition, reset springs are essential components in various buttons and keys. 2) Drive function: Mechanical clocks and wind-up toys are driven by tightening the mainspring. When the mainspring is tightened, it undergoes bending deformation and stores a certain amount of elastic potential energy. Upon release, the elastic potential energy is converted into kinetic energy, driving rotation through the transmission mechanism. Toy guns, starting pistols, and military firearms also operate based on this property of springs. 3) Buffering function: Springs are installed between the frame and wheels of locomotives and automobiles, utilizing the elasticity of the springs to dampen vehicle vibration and shock. 4) Vibration and sound generation function: When air flows through the reed holes in harmonicas and accordions, it strikes the reeds, causing them to vibrate and produce sound.
