Engine resonance: causes and DigiPlus fair valuesolutions Engine resonance is a well-known term in the field of mechanical design. When an engine or other components around it resonates while the engine is running, it will cause serious mechanical failures and even pose a threat to the safety of the driver. In this article, we will explain the causes of engine resonance and its solutions. What is engine resonance? Engine resonance refers to the vibration coupling of the parts of the engine with other parts of the surrounding environment during vibration, resulting in resonance. Resonance may cause a significant increase in the amplitude of engine parts, or even exceed its design load, resulting in mechanical wear and damage. Resonance is generated by excitation energy transfer. When the engine is running, all moving parts, including the engine support frame, crankshaft, connecting rod, piston, etc., will vibrate.These vibrations will be transmitted to other parts around the engine, such as chassis, body structure, etc., resulting in engine resonance. Causes of engine resonance There are many reasons for engine resonance. The following are some common reasons: 1. Design defects or poor material selection - When the engine design or material selection is defective, the engine may not be able to withstand the vibration required for normal operation, resulting in resonance. Two. The crankshaft and connecting rod are misaligned - if the connecting rod or crankshaft bearing is not suitable or aligned, it will also cause excessive vibration of the engine and resonance around the engine. 3. Unbalanced mass - When any component of the engine is unbalanced mass, the operation will cause vibration and may resonate in the surrounding parts. Four. Damage to the engine bracket - When the engine bracket is cracked, the screws are loose or otherwise damaged, it will cause excessive engine vibration and cause resonance around it.How to solve the engine resonance? Here are several ways to solve the engine resonance problem: 1. Improve the design of the drive system - a good design can reduce the occurrence of resonance. For example, by adjusting the crankshaft support frame or replacing the connecting rod, the engine resonance can be effectively suppressed. Two. Use higher quality parts materials - The use of higher quality materials can reduce the vibration of engine components and reduce the occurrence of resonance. 3. Redesign and replacement of the engine bracket - check whether the engine bracket is damaged and carry out necessary maintenance to eliminate resonance, or consider replacing a more suitable bracket. Four. Use the engine control system - the control system can be adjusted to control the vibration mode of the engine and avoid destructive resonance. In summary, engine resonance is a common problem, which may lead to serious mechanical failures.These resonance problems can usually be solved by redesigning or manufacturing better quality accessories. If you encounter engine resonance problems, please be sure to seek the advice of professional maintenance personnel to ensure your safety.
