With the development of military vehicles, the development of on-board electronic equipment has attracted more and more attention. In the process of moving, military vehicles bear many kinds of mechanical forces from the engine work and various complex road conditions in the field, which are affected by vibration and impact, and do great harm to vehicle electronic equipment. According to the survey, the failure rate of electronic equipment caused by vibration accounts for more than 80% of the total failure rate of electronic equipment. Such a high proportion indicates that the vibration is the most harmful to the on-board electronic equipment, which must be paid attention to.
Military vehicle electronic equipment such as vehicle borne radar, vehicle borne electronic support, vehicle borne missile, electronic communication and other precision equipment suffer from various mechanical forces in the training and battlefield environment, which is a great harm to the electronic equipment itself. The hazard mode is mainly due to the resonance of large amplitude generated by the equipment under a certain excitation frequency, which will eventually lead to damage due to the vibration acceleration exceeding the limit acceleration that the equipment can bear, and directly lead to damage or failure of the vehicle electronic equipment. Therefore, in the design of the vibration isolation system of the on-board electronic equipment, it is necessary to fully consider that the response value of the on-board electronic equipment under each excitation frequency is less than the limit that the equipment can bear, and protect the electronic equipment in the maximum sense, so as to make it more safe and reliable.
In the installation and design of the vibration isolator for military vehicle electronic equipment, considering the special function between the isolator and the vehicle frame, the function of using the puzmai damping block, puzmai damping plate and puzmai damping buffer block is to form a buffer between the impact force formed by the vibration isolator of the electronic equipment and the road surface, which is equivalent to an auxiliary spring, which can reduce the vibration effect of the road surface on the vehicle electronic equipment At the same time, the noise control of the whole vehicle also greatly improves the ride comfort.
Military on-board electronic equipment is more and more widely used and popularized in the modern military. More and more electronic equipment are assembled on-board electronic equipment of military vehicles, and damping vibration isolators are installed and used. The development of damping vibration isolation is more optimized towards the structural design, more scientific and reasonable layout, more safe and convenient use. The use of putsmier damping materials has environmental protection, safety, fire resistance and resistance Ultra low temperature, high temperature, humidity, dust and other long-term harsh environment to maintain excellent stability. In order to adapt to different road conditions, to achieve the purpose of vibration reduction and protection of on-board electronic equipment. At the same time, the damping and vibration isolator of vehicle electronic equipment will also be more efficient in structure. The development of damping and vibration isolator of vehicle electronic equipment is mainly in vehicle matching, and it is necessary to integrate the vehicle as a whole. In particular, the whole chassis, engine and transmission of the vehicle body, as vibration sources, affect the normal operation and work of the on-board electronic equipment. Therefore, in view of the complexity of the situation, the use of damping vibration isolators must meet the requirements of vehicle vibration reduction under complex conditions, so that the vehicle can be more safe and reliable in the use process, and the work of the electronic equipment will not be affected and interfered by external factors, so as to ensure the safety and reliability of the vehicle Maintain its own stability, provide guarantee for improving the safe driving coefficient of the vehicle, improve the comfort of riding, reduce the vibration of the on-board electronic equipment under the condition of great vibration, improve the applicability of the damping and vibration isolator of the on-board electronic equipment, conform to the development trend of the installation of the military on-board electronic equipment, and make more and more advanced electronic equipment It is possible to install it on the vehicle.
Scientific and reasonable design of damping and vibration reduction is applied to the damping system of on-board electronic equipment to reduce the vibration of on-board electronic equipment, protect on-board electronic equipment from various mechanical forces, reduce vibration and resonance, and ensure the use performance and safety performance of on-board electronic equipment. It is of great practical significance to improve the safety factor of vehicle driving, combat riding and driving, and meet the safety and stable use of the army in various complex environments.
