A vibration and shock fusion control method

Abstract

The invention discloses a vibration and shock fusion control method, which is applied to a vehicle including a suspension mechanism, including: 1. Based on a vibration and shock end-stop determination control method, a power flow vibration and shock fusion control method is established; 2. Based on the ceiling damping semi-active control method, the power flow analysis method is introduced to establish a power flow vibration control method; 3 Based on the "soft landing" impact idea, the power flow analysis method is introduced to establish a power flow impact control method. The present invention can realize smooth switching between two control methods of vibration and impact control, and at the same time accurately calculate the vibration control force and impact control force required by the suspension system, thereby greatly reducing the impact of vibration / shock on equipment and the human body s damage.

Description

Technical field [0001] The present invention relates to the field of active / semi-active suspension vibration and impact control, and is specifically a vibration and impact fusion control method. Background technique [0002] For engineering vehicles, special vehicles, such as special vehicles such as unconnected roads or non-pavements, as well as mechanical equipment such as landing gears, ships, etc., are difficult to avoid during operation. For vibration incentives, there are currently more control methods, which can achieve better vibration suppression effect, greatly reduce the damage caused by vibration to the human body, such as a ceiling damping control method. For impact incentives, due to their only in a particular environment or in the field of use, there is less related research, but there are also better impact control methods to be used. However, independently considering vibration excitation or impact incentives, researching their control methods, too idealization...

AI Technical Summary

Problems solved by technology

However, the switching control unit of this hybrid control method only judges the timing of switching based on whether the suspension stroke will be used up and the suspension limit will be hit. There is less consideration of contact, which is likely to cause a sudden change in the acceleration of the human body during the switching process, thereby causing damage to the equipment and the human body
