We have issued (version 04-01 issued on 2024-04-05) of our excel calculation tool for vehicles builders.

The sheet features:

• database of a number of host vehicles;
• custom host vehicle can be defined by user;
• you can define your loads at specific positions on the vehicle;
• you'll get calculated a center of gravity position and resultant load on front and rear axle;
• warnings appears if the max allowed load is exceeded for the selected host vehicle.

Features for a road and rail drive calculations:

• define number of axles (single front, single or double rear axle)
• single and double axle front and double axle rear bogie
• define pavement of road and wheels diameter. Program selects rolling resistance factor for your selection.
• define a rail wheels' diameter;
• define front and rear axle position;
• define the vehicle design travel speed;
• define the track uphill inclination;
• the sheet calculates front and rear rail axle load;
• the sheet calculates drive power needed to travel at the desired speed at defined uphill;
• you will be warned if the rail wheel base vs design speed doesn't comply EN 15746 criteria;
• you will be warned if the wheel load vs diameter doesn't comply EN 15746 criteria.
