Develop the right suspension for ATV

Zedling suspension specialists support ATV development teams to design the right suspension & achieve their target performance. Zedling Suspension team has worked extensively with various ATV development teams on challenging projects & realized the need for a software resource for an effective & efficient ATV development.

Zedling Suspension has developed ZedlingDashpot a software program to help ATV designers & teams develop the right suspension for their ATV in the shortest time.

Zedling Dashpot

Zedling Dashpot is specialized software program to aid ATV suspension design & analysis. The software delivers practical parameters of ATV shock absorber which are critical to achieve the optimum suspension performance.

ATV suspension development work involves complex linkages, its kinematics & dynamics. Achieving the optimum vibration isolation & right suspension dynamic travel is critical in order to complete the track & in short time. Zedling Dashpot is developed by Zedling Suspension team after extensive interaction with various ATV development teams asking tricky questions, facing challenges on suspension design & achieving the right solution.

Zedling Dashpot addresses the need of a software resource which can provide practical specifications of suspension components like spring stiffness, damping ratio, low & high-speed damping etc. For ATV development teams it is important to achieve the specifications of suspension components first time right in order to avoid expensive modifications & the need to buy additional components.

Zedling Dashpot is built with classical suspension theory as well as calculations developed by our team working with numerous ATV development projects achieving the target performance.

Guide

The following section helps you to learn how to utilize the zedling dashpot program.

After you are convinced with the features of Zedligndashpot you need to click on purchase & complete the payment process. You will enter your unique login id & password during the purchase of a license.

For utilizing the program you need to log in using this login id & password. Then you can click on program & you will find below input fields window.

Inputs

All input fields are mandatory. The contextual meaning of each input field parameter is available by clicking ? & you can find the same below:

Distance between the centers of the front & rear wheels.

Distance measured across front axle from the center line of one tire tread to the center line of the opposite tire tread

Distance measured across rear axle from the center line of one tire tread to the center line of the opposite tire tread.

This includes the complete ATV weight including any instrumentation if any & the rider with all riding gears.

Percentage distribution of total weight (with driver) towards front wheels.

Mass of the front suspension, front wheels & components attached to these systems constitute the unsprung

Mass of the rear suspension, rear wheels & components attached to these systems constitute the unsprung.

Height from the ground of the point at which the total weight of ATV including the rider is evenly dispersed.

Height from the ground of C.G point of front unsprung mass. This is different than complete ATV C.G height & usually near to front axle height.

Height from the ground of C.G point of rear unsprung mass. This is different than complete ATV C.G height & usually near to rear axle height.

It is the ratio of the displacement of the point of interest to that of another point. Here it’s the mathematical ratio of front wheel travel to front suspension total stroke. Usually, front wheel travel is higher than front suspension stroke due to the linkage, hence this ratio is usually greater than.

It is the ratio of the displacement of the point of interest to that of another point. Here it’s the mathematical ratio of rear wheel travel to rear suspension total stroke. Usually, rear wheel travel is higher than rear suspension travel due to the linkage, hence this ratio is usually greater than.

Front roll center is the height from the ground of the notional point at which the cornering forces in the rear suspension are reacted to the vehicle body

Rear roll center is the height from the ground of the notional point at which the cornering forces in the front suspension are reacted to the vehicle body.

It is the change in velocity per unit time during cornering of a vehicle in terms of gravity “g”. Typically this is 1 to 1.5 g.

 It is the change in velocity per unit time during braking of the vehicle in terms of gravity “g”. Typically this is 1 to 1.2 g

It is the change in velocity per unit time during vehicle crossing over bumps in terms of gravity “g”. Typically this is 3-5 g.

This is the stiffness of tyre in a radial direction measured as a force to deflect the tyre per unit of deflection. Tyre shall be inflated to correct pressure for this measurement.

 This is the total vertical travel available for the front wheel from “wheel in air” condition to “wheel full bump condition” without interfering with other ATV components.

This is the total travel available for the front wheel from “wheel in air” condition to “wheel full bump condition” without interfering with other ATV components.
