HiT Clutch Slippage Simulation

What is ADAMS?

Application: ADAMS SIMULATION

ADAMS (Automatic Dynamic Analysis of Mechanical System) or MD ADAMS (Adams for Multibody Dynamics) is a simulation application software for developers and engineers to build and test virtual mechanical prototypes. It is one of the most popular software for mechanical module analysis.

HiT Clutch Slippage simulation - background

What data do we have?

We used three different Clutch Springs with k-value of 30, 50 and 74, respectively. The larger k-value Clutch Spring (or, say, the stronger it is), the later Clutch engagement happens. By observing the spring rpm at different phases, including Not Engaged, Slippery Contact, and Fully Engaged, we will see the difference between HiT Clutch and stock clutch (i.e., conventional clutch).

Definition

Not Engaged: The Clutch hasn’t touched the Bell yet.
Slippery Contact: The Clutch touches the Bell in slippery contact situation.
Fully Engaged: The Clutch rotates synchronously with the Bell.

Stock clutch (Conventional clutch)

HiT Clutch Slippage simulation - Stock clutch 74N

Spring K-Value (N/mm)	Slippery Contact Start (RPM)	Fully Engaged Start (RPM)
30	2900	5300
50	3750	6000
74	4600	6800

HiT Clutch

Spring K-Value (N/mm)	Slippery Contact Start (RPM)	Fully Engaged Start (RPM)
30	3000	5300
50	3750	6000
74	4600	6800

For stock clutch, the rpm difference between Slippery Contact Start and Fully Engaged Start is about 2300rpm, showing much longer time to get fully engagement. BAD engaging ability.
For HiT Clutch, the rpm difference between Slippery Contact Start and Fully Engaged Start is about only 500rpm, showing much effective engaging ability. WIN!!
Clutch Springs with different K-value may affect the Not Engaged and Fully Engaged intervals, it does not affect the Slippery Contact interval.

For example, using Clutch Springs with k-value of 30, 50, or 74(N/mm) results in similar Slippery Contact interval: about 2300rpm difference in stock clutch, and only 500rpm in HiT Clutch.
