Introduction

Welcome to the Lift and Escalator Symposium 2022! In this presentation, we will be discussing the generation and application of dynamic lift kinematics. Lift kinematics refers to the study of a lift car's motion without reference to mass or force, focusing on the passenger experience. We will explore why dynamic lift kinematics is necessary, how it is calculated, and its impact on lift systems. Additionally, we will discuss the improvements it brings to lift performance and monitoring. So, let's dive in!

Background Information

Before delving into the concept of dynamic lift kinematics, let's provide some background information. Dynamic lift kinematics is a field of study that deals with the motion of lift cars, considering factors such as acceleration, deceleration, and velocity. By understanding lift kinematics, we can better analyze lift traffic and make improvements to enhance passenger experience.

What is Lift Kinematics?

Lift kinematics refers to the study of how a lift car moves without taking into account the effects of mass or force. It focuses on understanding how passengers feel during their ride, including factors such as waiting time, smoothness of the ride, and any discomfort, such as ear popping. Lift kinematics is controlled by a variable speed drive, which follows an idealized kinematics plot to ensure a pleasant and efficient Journey.

Why Do We Need Dynamic Lift Kinematics?

Dynamic lift kinematics is crucial for accurate lift traffic analysis. By considering dynamic profiles, such as asymmetric or dynamic acceleration Patterns, we can improve lift performance and safety. For instance, in lift systems with two cars in a shaft, the lower car may need to wait for the upper car to depart to avoid collisions. By using an asymmetric acceleration profile, we can optimize the timing of both cars, enhancing efficiency and safety.

How to Calculate Dynamic Lift Kinematics

Calculating dynamic lift kinematics involves splitting the lift journey into periods. Each period represents a section of time where the lift maintains a constant jerk. For symmetric profiles, traditional equations can be used to calculate each period. However, for asymmetric profiles, there is a need to calculate twice as many acceleration values and four times as many jerk values. The use of computational methods can approximate the area under the profile, allowing for the modeling of dynamic and asymmetric profiles.

Modeling Asymmetric Lift Kinematics

Modeling asymmetric lift kinematics is essential for lift maintenance. Asymmetric profiles may result in impurities and false readings if an accelerometer, which is used to monitor kinematics, assumes symmetric profiles. By accurately modeling asymmetric kinematics, maintenance officers can ensure the lift systems perform as intended and identify any deviations from desired profiles. This knowledge aids in maintaining lift safety and efficiency.

Impact of Dynamic Profiles on Lift Systems

Dynamic profiles have various impacts on lift systems. In lift systems with two cars in a shaft, altering the acceleration profiles can improve safety and reduce collision risks. It also allows lifts to operate closer together, optimizing traffic flow. Additionally, dynamic profiles can address prolonged leveling delays, which are common in older lift systems with tall buildings. By monitoring and analyzing lift kinematics, it becomes possible to identify inefficiencies and make necessary adjustments.

Improving Performance in Lift Systems with Two Cars

Dynamic lift kinematics has significant benefits for lift systems with two cars in a shaft. By adjusting acceleration profiles, the lower car can depart earlier, as it no longer needs to wait for the upper car to clear the path. This improvement in timing ensures efficient utilization of the lift system and eliminates any safety concerns related to simultaneous departures.

Improving Performance in Multi-dimensional Lift Systems

Multi-dimensional lift systems benefit from dynamic lift kinematics by allowing for more accurate traffic analysis. By considering factors such as asymmetric profiles, different speeds, and complex acceleration patterns, the performance of multi-dimensional lifts can be optimized. This optimization leads to better passenger experiences and improved overall efficiency in buildings with complex lift systems.

Improvements in Lift Monitoring

One of the significant advantages of dynamic lift kinematics is the ability to improve lift monitoring. By accurately modeling lift profiles, maintenance officers can identify deviations from desired patterns, allowing for proactive maintenance and preventing potential issues. This improved monitoring ensures a safer and more reliable lift experience for passengers.

Conclusion

In conclusion, dynamic lift kinematics plays a pivotal role in enhancing lift performance and passenger experience. By accurately modeling lift profiles and considering factors such as asymmetric and dynamic acceleration patterns, we can optimize lift systems, improve traffic flow, and ensure passenger safety. The ability to monitor lift kinematics more precisely enables maintenance officers to identify and address any deviations from desired profiles promptly. With continuous advancements in lift technology, dynamic lift kinematics will Continue to Shape the future of efficient and comfortable vertical transportation systems.
