Compliant Mechanisms Designs in Automotive Industry
Updated: Mar 30
In our previous blog articles, we have seen the applications of compliant mechanisms in the medical field. Let us now explore various compliant designs in the automotive industry.
1. Passenger Ergonomics
Compliant mechanisms by their definition include flexible components. Efforts have been made to improve passenger ergonomics by redesigning seats, steering wheel and pedals. In addition, for the rest of the vehicle transmission, a reduction in the number of joints also gives the mechanism high precession. Vibration and noise caused by the turning and sliding joints of rigid body mechanisms can also be eliminated up to some extent using compliant mechanisms. Vibrations and road noise that are transmitted to the chassis from the forces exerted at the wheel also reduce the comfort level of the passenger.
2. Suspension System
Suspension System includes tyres, springs, shock absorbers, arms, linkages, bushing and joints. The use of compliant mechanisms has many advantages. The possible advantages of their use in
suspension systems include:
Reduced number of joints
Reduced number of parts
Energy storage in flexible members
Reduced manufacturing and assembly costs
Compliant mechanisms used in suspensions take advantage of utilizing flexibility for motion and energy storage. This has the potential for reducing parts, cost, space and weight when compared to traditional mechanisms.
3. Driving Safety
Consider an example of a compliant mechanism wiper which was produced by FLexSys.
This reduces part count and also significant cost savings.
