Introduction

ZedlingDashpot is developed with the aim to provide a practical & powerful tool to ATV development teams which is easy to use & provide results which have physical significance. ZedlingDashpot can be used to simulate the ATV suspension properties & provides a detailed output & visualization in terms of graphical results.

 

System requirements

Zedlingdashpot is a modern web-based program which does not need any elaborate software installation. It needs internet connectivity for license activation, using the program and generating the outputs.

Operating system: Microsoft Windows XP or Microsoft Windows Vista or Microsoft Windows 7 or higher

Microsoft Excel version 10 or higher for export of data

Licensing

Zedlingdashpot comes with six months of a full-time key which can be transferred from one computer to other. During activation, you need to provide your name & email address.

 

START

The following section helps you to learn how to utilize the zedlingdashpot 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:

 

 

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

 

  1. Wheelbase: Distance between the centers of the front & rear wheels
  2. Wheel track: Distance measured across front axle from the center line of one tire tread to the center line of the opposite tire tread
  1. Wheel track: Distance measured across rear axle from the center line of one tire tread to the center line of the opposite tire tread
  2. Total weight with driver: this includes the complete ATV weight including any instrumentation if any & the rider with all riding gears
  3. Weight distribution front in %: Percentage distribution of total weight (with driver) towards front wheels
  4. Unsprung mass front: Mass of the front suspension, front wheels & components attached to these systems constitute the unsprung
  5. Unsprung mass rear: Mass of the rear suspension, rear wheels & components attached to these systems constitute the unsprung
  6. C.G height: Height from the ground of the point at which the total weight of ATV including the rider is evenly dispersed
  7. Front unsprung mass C.G height: 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
  8. Rear unsprung mass C.G 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
  9. Front suspension motion ratio: 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
  10. Rear suspension motion ratio:  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
  11. Front roll center height: Front 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
  12. Rear roll center height: 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
  13. Cornering acceleration: 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
  14. Braking acceleration: 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
  15. Bump acceleration: 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.
  16. Tyre rate: 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.
  17. Allowable front full wheel travel: 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.
  18. Allowable front full wheel travel: 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.

 

After the user enters all the input fields you need to click on Zedlingdashput_output to generate the results. All the input parameters shall be entered in the specified units for correct results.

 

Example output results are shown below:

 

 


 

 


 


 


The output parameters & graphs can be printed for discussions/review using the print option. Also, the complete case including the input & output can be exported in Microsoft Excel for records/analysis.

 

All the cases entered can be saved on our servers which can be retrieved during the license activation period.
